利用原子转移自由基聚合反应合成了以聚苯乙烯 -b-聚 (乙烯 -co-丙烯 ) ( SEP)为主链、无规分布且数目可控的聚甲基丙烯酸乙酯 ( PEMA)为支链的嵌段接枝共聚物 SEPG.发现在甲苯中因支链 PEMA与聚 (苯乙烯 -co-对六氟羟丙基 -α-甲基苯乙烯 ) [简称 PS( OH]的氢键络合作用和 EP嵌段的溶解作用导致了聚集体的胶束化 .研究了胶束的尺寸及其分布对 PS( OH)中羟基含量和共混物组成的依赖性 .
Polymerization of polystyrene-b-poly (ethylene-co-propene) (SEP) as the main chain, a random distribution of controlled number of polymethylmethacrylate (PEMA) was supported by atom transfer radical polymerization Chain block graft copolymer SEPG found in toluene due to the branched PEMA and poly (styrene-co-hexafluorohydroxypropyl-α-methyl styrene) [referred to as PS (OH] hydrogen bonds The cohesion and the dissolution of the EP block led to the micelle formation of the aggregates.The dependence of the size and distribution of the micelles on the hydroxyl content and the composition of the blend in PS (OH) was studied.
