| 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.

| Abstract: | 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. |
