Understanding and preventing the formation of deformed polymer particles during synthesis by a seeded polymerization method
01-05-2011 | Srisopa, Anong; Imroz Ali, A. M.; Mayes, Andrew G., Journal of Polymer Science Part A: Polymer Chemistry, 2011
Abstract Uniformly sized porous polymer particles with different polarity namely poly(divinylbenzene), poly(vinyl acetate‐co‐divinylbenzene), poly(ethylene dimethacrylate), and poly (glycidyl methacrylate‐co‐ethylene dimethacrylate) were prepared in the micron‐size range by a seeded ...
Versatile functionalization of polyester hydrogels with electroactive aniline oligomers
01-05-2011 | Guo, Baolin; Finne‐Wistrand, Anna; Albertsson, Ann‐Christine, Journal of Polymer Science Part A: Polymer Chemistry, 2011
Abstract Functionalizing aliphatic polyester hydrogels with an aniline oligomer is a means of achieving electrically conductive and degradable hydrogels. To lower the aniline oligomer content while maintaining a high conductivity and to overcome the acidic degradation product from ...
Fluorinated vinyl ether homopolymers and copolymers: Living cationic polymerization and temperature‐induced solubility transitions in various organic solvents including perfluoro solvents
01-05-2011 | Shimomoto, Hiroaki; Fukami, Dai; Kanaoka, Shokyoku; Aoshima, Sadahito, Journal of Polymer Science Part A: Polymer Chemistry, 2011
Abstract Partially fluorinated poly(vinyl ether)s with C4F9 and C6F12H groups in the side chain were synthesized via living cationic polymerization in the presence of an added base in a fluorine‐containing solvent, dichloropentafluoropropanes. For comparison, the polymerization of vinyl ...
Synthesis and micellization of new biodegradable phosphorylcholine‐capped polyurethane
01-05-2011 | Wang, Zhigao; Wan, Pengjun; Ding, Mingming; Yi, Xuan; Li, Jiehua; Fu, Qiang; Tan, Hong, Journal of Polymer Science Part A: Polymer Chemistry, 2011
Abstract To obtain controllable and biocompatible drug carriers, a series of amphiphilic biodegradable multiblock polyurethanes end‐capped by phosphorylcholine were designed and synthesized using L‐lysine ethyl ester diisocyanate (LDI), poly(lactic acid)‐poly(ethylene glycol)‐poly(lactic ...
Radical polymerization of 1‐alkenes catalyzed by lithium salts of carboranes
01-05-2011 | Janata, Miroslav; Vlček, Petr; Látalová, Petra; Svitáková, Romana; Kaleta, Ji ..., Journal of Polymer Science Part A: Polymer Chemistry, 2011
Abstract Radical polymerization of selected 1‐alkenes, (1‐hexene, 1‐octene and 2‐methyl‐1‐heptene), initiated with classical radical initiators and catalyzed by lithium salts of selected carboranes was studied. In accordance with recently published results it was found that the use of ...
Thermoresponsive star triblock copolymers by combination of ROP and ATRP: From micelles to hydrogels
01-05-2011 | Zhu, Weipu; Nese, Alper; Matyjaszewski, Krzysztof, Journal of Polymer Science Part A: Polymer Chemistry, 2011
Abstract Novel biocompatible, biodegradable, four‐arm star, triblock copolymers containing a hydrophobic poly(ε‐caprolactone) (PCL) segment, a hydrophilic poly(oligo(ethylene oxide)475 methacrylate) (POEOMA475) segment and a thermoresponsive poly(di(ethylene oxide) methyl ether ...
Sugar‐based hydrophilic polyurethanes and polyureas
01-05-2011 | Begines, Belén; Zamora, Francisca; Roffé, Isaac; Mancera, Manuel; Galbis, Juan A., Journal of Polymer Science Part A: Polymer Chemistry, 2011
Abstract Novel linear homogeneous polyurethanes and polyureas with enhanced hydrophilic character have been successfully prepared from sugar‐based monomers having their hydroxyl groups free or partially protected. By the reaction of primary hydroxyl groups of xylitol with dimethyl ...
Linear tetrablock quaterpolymers via triple click reactions, azide‐alkyne, diels–alder, and nitroxide radical coupling in a one‐pot fashion
01-05-2011 | Durmaz, Hakan; Hizal, Gurkan; Tunca, Umit, Journal of Polymer Science Part A: Polymer Chemistry, 2011
Abstract Azide‐alkyne and Diels–Alder click reactions together with a click‐like nitroxide radical coupling reaction were used in a one‐pot fashion to generate tetrablock quaterpolymer. The various living polymerization generated linear polymers with orthogonal end‐functionalities, ...
