Polyaddition in miniemulsions: A new route to polymer dispersions - Miniemulsification of polyfunctional epoxides with varying diamines, dithiols, or bisphenols and subsequent heating to 60(degree)C yields polymer latexes with narrow size distribution (see TEM micrograph). The materials presented here are the first polyaddition-derived miniemulsion latexes. The molecular weight distributions around 2 indicate that almost ideal heterophase polymerization conditions are preserved throughout the course of the reactionLandfestert, K. et al. | 2000

A self-doped oligoaniline with two stable redox couples in a wide pH range - Aniline-2,3-dicarboxylate is polymerised in aqueous solution in the presence of sodium peroxodisulfate. XPS analysis reveals the novel poly(aniline) to exhibit 61% of the quinoid and 39 % of the benzenoid structure. The degree of self-doping is 21%. The polymer shows two reversible, single-electron transfer redox steps (see curve b in the figure) over a wide pH range. Both redox processes involve single-proton transfer in every two monomer units, which is considerably different from conventional polyaniline (curve a in the figure)Yamamoto, K. et al. | 2000

Aluminium and rare earths alkoxides as initiators for the heterogeneous anionic coordinated polymerisation of propylene oxide. A 1H NMR approach of the regioselectivity and transfer ability of the catalytic system - The regioselectivity of the first monomer insertion during the heterogeneous anionic coordinated polymerization of propylene oxide is studied by 1H NMR spectroscopy. Aluminium benzyl oxide, chemically grafted onto a porous support was used as the standard initiator system. It shows that the regioselectivity of first-monomer insertion reflects the placement of the monomer units in the chain, which allows the comparison of different catalyst systems. The mechanism of allyl group formation is discussed (see Scheme)Jacquier-Gonod, V. et al. | 2000

Reactive groups on polymer coated electrodes, 12. New conducting carrier materials: Polyalkylthiophene functionalized with amino group and its protected forms - The synthesis and electropolymerization of amino-functionalized 3-alkylthiophenes are reported. Due to strong electrical interference of the amino group, electropolymerization is completely inhibited, but protection thereof considerably improves the electropolymerization features. The polymers obtained are electrochemically stable and show distinct solvatochromic behavior. The figure shows an SEM micrograph revealing the surface morphology of the N-trifluoroacetamido-substituted polymerLi, G. et al. | 2000

Synthesis and characterization of non-covalent liquid crystalline diblock copolymers - Diblock copolymers of the structure poly- (dimethylaminoethylmethacrylate)-b-poly-(methacrylic acid) (polyDMAEMA-b-polyMA) are used as precursors for the synthesis of liquid crystalline (LC) diblock copolymers. The LC products are a result of attractive, noncovalent interaction. The self-assembly of the copolymers is studied by SAXS, which reveals typical LC structures in combination with microphase separation structures of block copolymers. The optical micrograph shown in the figure shows a typical smectic textureGohy, J.-F. et al. | 2000

Preparation and characterization of aromatic polybenzoxazoles bearing ether and 1,4-naphthalene or 2,6-naphthalene units in the main chain - Novel high-molecular-weight poly(o-hydroxyamide)s are synthesized by low-temperature solution polycondensation of 4,4'-(1,4-naphthalenedioxy)dibenzoyl chloride and 4,4'-(2,6-naphthalenedioxy)dibenzoyl chloride with different bis(o-aminophenol)s. Subsequent thermal cyclodehydration affords the corresponding polybenzoxazoles (see Scheme). While the precursor polymers are soluble in a variety of solvents, almost all of the thermally very stable polybenzoxazoles are found to be insolubleLiou, G.-S. et al. | 2000

Modification with alkyl chains and the influence on thermal and mechanical properties of aromatic hyperbranched polyesters - All-aromatic hyperbranched polyesters bearing terminal hydroxy groups are functionalized with aliphatic n-alkyl carboxylic acids. Due to reduced intermolecular hydrogen bonding, both an increasing degree of modification and an increasing length of the alkyl chain cause a decrease in glass transition temperatures. The complex phase behavior of some of the products are discussed in terms of amphiphilicity, microphase separation and macroscopic demixingSchmaljohann, D. et al. | 2000

Studies of atom transfer radical polymerization (ATRP) of acrylates by MALDI TOF mass spectrometry - Atom transfer radical polymerization a (ATRP) of acrylates is investigated in the presence of high concentrations of ethyl-2- bromopropionate as the initiator and CuBr-amine as the catalyst. Mass spectrometric analysis reveals that in the course of polymerization bromine-terminated macromolecules are converted into inactive bromine-free species. The figure shows (a) observed and (b) calculated isotope distributions of poly(butyl acrylate) (the degree of polymerization is 10): (IBednarek, M. et al. | 2000

The synthesis and characterization of a nematic liquid crystalline network, 3. Network formation, dynamic and quasistatic mechanical behaviour - The crosslinking reaction of a main-chain liquid crystalline (LC) prepolymer (the reaction is schematically shown in the Figure) is investigated. The percolation model describes the dynamic scaling properties of the system, as evidenced by a power law behavior of the storage and loss modulus at the gel point over the whole frequency range. The stress-strain properties of the networks presented here can be described with a model, which combines elasticity, yield phenomena and plasticityHeinrich, S.Richter G. et al. | 2000

New insights into the mechanism of 1,2-bis- (trimethylsilyloxy)tetraphenylethane-induced free radical polymerization: Application to the synthesis of block and graft copolymers - The role of both initiator and terminator during the radical polymerization is adopted by 1,2-bis(trimethylsilyloxy)tetraphenylethane (TPSE). For methyl methacrylate, chain propagation is controlled by reversible deactivation of growing polymeric radicals (the figure shows the variation of molecular weight with conversion for methyl methacrylate). For styrene the mechanism is more complex: Chain growth involves degenerative transfer of TPSE hemifragments from chain to chain, which can cause irreversible terminationLeon-Sáenz, E.De et al. | 2000

Polyion complex fiber and capsule formed by self-assembly of chitosan and gellan at solution interfaces - Characteristic surface morphologies are observed for the polyion complex consisting of chitosan and gellan gum. The complexes form as a result of spontaneous supramolecular self-assembly driven by attractive electrostatic interaction. Strong fibers with a tensile strength of 18.4 kg-mm2 and a knotting strength of 3.0 kg-mm2 can be drawn from this material by gravitation or wet-spinning (the SEM image shows the fiber morphology). The dyeability of these complexes with different types of textile dyes are studiedYamamoto, H. et al. | 2000

Saccharide polymers, 3. Synthesis and polymerization of a 5,6-unsaturated fructofuranoid derivative - A four-step reaction sequence produces a new exo-fructofuranoid monomer, which undergoes radical polymerization' Homo- and copolymerizations under different reaction conditions are presented. The glass transition temperatures of the copolymers are shown to rise with the sugar concentration in the polymers. The saccharide copolymers are optically active and show negative optical rotation which increases with the sugar content (the dependence is demonstrated in the figure for the methyl acrylate copolymers)Wick, S. et al. | 2000

An active catalyst system for proton reduction composed of a bipyridyl platinum complex and a polymer membrane - Electrocatalysis for H+ reduction by bis(2,2'-bipyridyl) platinum(II) in a polymer matrix is studied by cyclic voltammetry. Substantially increased activity of this system is observed (see cyclic voltammograms; a: Membrane-incorporated catalyst, b: Graphite electrode) as compared with conventional platinum-black. The mechanism of the process is investigated by XPS spectroscopy, which provides evidence for the formation of Pt(O), thus indicating that electrolysis starts after electrochemically producing the catalytically active speciesAbe, T. et al. | 2000

Star-shaped poly((trimethylene carbonate)-(co)-(e-caprolactone)) and its block copolymers with lactide-glycolide: Synthesis, characterization and properties - Different polyol initiators and catalysts are employed for the synthesis of linear and star-shaped trimethylearbonate-e-caprolactone copolymers. When dipentaerydiritol is used as the initiator low-molecular-weight crosslinked rubber materials are obtained. This network formation is a result of in-situ generation of crosslinker molecules by reaction of the crosslinker with trimethylcarbonate. The low-molecular-weight networks are used as macroinitiators for subsequent lactide-glycolide polymerizationJoziasse, C.A.P. et al. | 2000

Towards highly functionalized and semi-rigid polyzwitterions, 2. Poly(zwitterionic isocyanide)s: Synthesis and specific properties - Selective quaternization of the tertiary amino group in N,N-dimethyl-N-(3-isocyanopropyl) amine with 1,3-propanesultone or 2,2-dicyanoketene ethylene acetal and subsequent polymerization yields zwitterionic semi-rigid polyisocyanides. Gels formed by these polymers and ethylene glycol are birefringent (see optical micrograph in the figure, the gel contains 56 vol-% polymer) and show nematic order. They dissolve considerable amounts of salt to form birefringent blends, which display a high degree of long-range orderBieglé, A. et al. | 2000

Fabrication of a gradient refractive index (GRIN) plastic rod using the novel process of centrifugal diffusing polymerization - GRIN (gradient refractive index) plastics not to be laughed at! A new method of fabrication uses the centrifugal diffusion polymerization (CDP) technique. Methyl methacrylate as the reactive monomer and diphenyl sulfide as the dopant are used in an AIBN-initiated polymerization. The effects of the feed ratio, amounts of added acrylic polymers and reaction conditions are presented.

4-(tert-Butoxycarbonyloxy)benzyl p-toluenesulfonates as acid amplifiers applicable to chemically amplified photoresists - Acid amplifiers act autocatalytically by generating p-toluenesulfonic acid while being polymerized. Among the compounds tested, 4-(tert-butoxycarbonyloxy)-3-nitrobenzyl p-toluenesulfonate is shown to be the most superior for the purpose of improving the photo-sensitivity of photoimaging materials, because it is thermally stable in the absence of the acid. This compound, when coupled with a chemically amplified photoresist system, enhances the photosensitivity by a factor of 5Ito, H. et al. | 2000

Improved Suzuki polycondensation: A diiodo versus a dibromo monomer - Palladium-catalyzed coupling of aromatic diboronic acids with dihalogenated monomers is investigated depending on the kind of the halogen substituent. It shows that the diiodo-substituted monomers yields higher molecular weights than its dibromo-substituted analog. At the same time side reactions, such as the incorporation of phosphorus, is reduced. The influence of the catalyst quality is also studied: Even ageing for as short as 7 days in an inert atmosphere has a considerably detrimental effectSchlüter, S. et al. | 2000

Hydrogels based on modified chitosan, 1. Synthesis and swelling behavior of poly-(acrylic acid) grafted chitosan Full Paper: Grafting with poly(acrylic acid) chains is an efficient method of introducing a high number of hydroxyl groups into chitosan. The reaction is carried out in a homogeneous aqueous phase using potassium persulfate and ferrous ammonium sulfate as the redox initiator system. The level of grafting can be controlled via the iron cocatalyst concentration. The swelling behavior of the modified chitosan is studied as a function of pH and salt concentration. The Figure shows the swelling curves of two polymers at pH 2 (circles: 115, triangles: 524% grafting)Yazdani-Pedram, M. et al. | 2000

The aggregation of EAA plays a crucial role for the final polymer composition: While high MI feed ratios allow homopolymerization of MI besides copolymenzation and therefore causes MI to be incorporated to a greater extent, the aggregation of EAA at low MI feed ratios is the limiting factor of copolymerizing MIShi, L. et al. | 2000

Optical activity is observed for the hydrolyzed product P2, but also for polymer P1 (see Scheme), in which ease it is attributed to the homochiral pantolactone and the S-configured C-2 carbon of the main chainMontembault, V. et al. | 2000

The kinetic studies presented here reveal that the two polymerizations show significant differences with respect to the role of the initiator: During the polymerization of styrene DCT acts as a bifunctional initiator (see Scheme, top), while during the polymerization of methyl methacrylate DCT is monofunctional (see Scheme, bottom)Neumann, A. et al. | 2000

Radical telomerization of 1,3-butadiene with perfluoroalkyl iodides - Full Paper: The radical telomerization of 1,3-butadiene in the presence of 1-iodoperfluorohexane and 1-iodoperfluorooctane (RFI) is studied. The best reaction conditions are found to be the use of di-tert-butyl peroxide as initiator at 140-150(degree)C in acetonitrile. The transfer constant is determined for the transfer of the fluorinated species onto 1,3-butadiene which gives rise to the formation of nonfunctional oligomers at high butadiene-RFI ratios. The conversion profiles of both the monomer (*) and RFI are presented in the FigureLebreton, P. et al. | 2000
