| 摘 要： | 通过丙烯酸叔丁酯的自由基调聚和苯乙烯的原子转移自由基聚合（ATRP）法合成了聚丙烯酸叔丁酯-聚苯乙烯（PtBA-b-PS）嵌段共聚物,然后在三氟乙酸作用下进行选择性水解得到了两亲性聚丙烯酸-聚苯乙烯（PAA-b-PS）嵌段共聚物。利用1H-NMR、FT-IR和GPC对产物的结构进行了表征。采用透析法制备了PAA-b-P...

| Abstract: | Poly(tert-butyl acrylate-b-styrene)(PtBA-b-PS) block copolymer was synthesized by radical telomerization of tert-butyl acrylate(tBA) and atom transfer radical polymerization of styrene.Poly(acrylic acid-b-styrene)(PAA-b-PS) amphiphilic block copolymers were obtained by selective hydrolysis in the presence of trifluoroacetic acid,which were characterized by 1H-NMR,FT-IR and GPC.The amphiphilic block copolymeric micelles were prepared by dialysis against water.Laser particle size analyzer and transmission ele... |
