摘要
采用氯化亚铁(FeCl2)/亚胺基二乙酸(IDA)催化体系引发对氯甲基苯乙烯的原子转移自由基聚合,获得端基和线性单元上含有多个氯原子的超支化聚对氯甲基苯乙烯(PCMS).并以此为大分子引发剂再次引发甲基丙烯酸特丁酯(tBMA)进行原子转移自由基聚合,制得了具有超支化核的星状接枝共聚物P(CMS-g-tBMA),所得产物在酸性条件下水解后得到两亲性超支化星状共聚物P(CMS-g-MAA).
A hyperbranched poly(chloromethyl styrene), PCMS was prepared by the atom transfer radical polymerization (ATRP) that was catalyzed by FeCl2/IDA catalyst system. Then the ATRP was used once again with the hyperbranched PCMS as initiator and tert-butyl mathacrylate(t-BMA) as monomer. A star-shaped graft copolymer with a hyperbranched core, P (CMS-g-tBAM) was obtained. Finally an amphiphilic star-shaped graft copolymer with a hyperbranched core and a number of hydrophilic arms,P(CMS-g-MAA), was obtained through hydrolysis of P(CMS-g-tBMA) under acidic condition.
