Atom transfer radical polymerization of styrene initiated by the novel initiator 2-bromo-2-nitropropane

Wang, Gang; Zhu, Xiulin; Zhengping, Cheng; Zhu, Jian

2005 e-Polymers

doi:10.1515/epoly.2005.5.1.357

AbstractHeterogeneous atom transfer radical polymerization (ATRP) of styrene initiated by 2-bromo-2-nitropropane in bulk was carried out with CuCl/2,2′-bipyridine as the catalyst. The kinetics was first order in monomer and the numberaverage molecular weight of the polymer increased linearly with...

Enhancement of sensitivity and selectivity in surface plasmon resonance detection of a DNA point mutation by polymeric microspheres

Kawaguchi, Haruma; Sato, Yasunobu; Okumura, Aya; Kyo, Motoki

2005 e-Polymers

doi:10.1515/epoly.2005.5.1.521

AbstractPolymeric microspheres were used to enhance sensitivity and selectivity in the detection of DNA point mutations with a surface plasmon resonance (SPR) biosensor. First, single-strand DNA probes were immobilized onto epoxy group derivatized gold surfaces and the hybridization of DNA...

Determination of chemical composition and molar mass distribution of random styrene-ethyl acrylate copolymers by high-throughput liquid chromatography

Romero, Iván García; Bashir, Mubasher Ahmed; Pasch, Harald

2005 e-Polymers

doi:10.1515/epoly.2005.5.1.832

AbstractSynthesis and characterization of random copolymers by spectroscopic and chromatographic techniques are normally slow and expensive because most measurements are conducted consecutively and no high-throughput techniques are used. In the present work parallel synthesis and high-throughput...

Antimicrobial activity of polystyrene particles coated by photo-crosslinked block copolymers containing a biocidal polymethacrylate block

Lenoir, Sandrine; Pagnoulle, Christophe; Detrembleur, Christophe; Galleni, Moreno; Jérôme, Robert

2005 e-Polymers

doi:10.1515/epoly.2005.5.1.783

AbstractA commercially available poly(ethylene-co-butylene) copolymer, endcapped by a short polyisoprene block and a hydroxyl group (PI-b-PEB-OH), has been derivatized into a macroinitiator for atom transfer radical polymerization (ATRP) by esterification of the hydroxyl end-group by an activated...

Modification of polymers by ultrasound treatment in aqueous solution

Rokita, Bozena; Czechowska-Biskup, Renata; Ulanski, Piotr; Rosiak, Janusz M.

2005 e-Polymers

doi:10.1515/epoly.2005.5.1.261

AbstractUltrasound treatment, as an alternative to chemical and radiation-based processes, is an interesting technique for the modification of average molecular weights of natural and synthetic polymers in aqueous solution. Degradation is the observed main effect for strongly hydrophilic...

Rheological characterization of polymer-based nanocomposites with different nanoscale dispersions

Seong, Dong Gi; Kang, Tae Jin; Youn, Jae Ryoun

2005 e-Polymers

doi:10.1515/epoly.2005.5.1.38

AbstractPolyamide 6 - clay nanocomposites with different nanoscale dispersions were prepared by melt compounding via twin-screw extrusion and their internal structures were characterized by X-ray diffraction (XRD) and transmission electron microscopy (TEM). The rheological behaviour of these...

Synthesis and characterization of novel organosoluble aromatic copolyimides

Yang, Jintian; Huang, Wei; Zhou, Yongfeng; Yan, Deyue; Wang, Xiaohang

2005 e-Polymers

doi:10.1515/epoly.2005.5.1.695

AbstractA series of novel aromatic copolyimides was synthesized from pyromellitic dianhydride with the commercial diamine 4,4’-methylenebisaniline (MBA) and the diamine 4,4’-methylenebis(2-tert-butylaniline) (MBTBA) specially designed by ourselves. The solubility of the copolyimides in...
