摘要
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 .
The complexation in toluene between SEPG, which was prepared by atom transfer radical polymerization(ATRP) with a block graft architecture, and PS(OH) via hydrogen bonding was investigated by viscometry and laser light scattering(LLS). In the process of complexation the soluble complex micelles were formed. The viscosity measurements confirm the stable micellization based on hydrogen bonding. The LLS results revealed the dependence of the size and its distribution of the complex micelles on both hydroyl content in PS(OH) and blend composition.
