【摘要】 众所周知,两亲嵌段共聚物可以在恰当的选择性溶剂中进行自组装,这些溶剂包括水^[1],正构烷烃^[2],和低碳链醇^[3]等。本文通过可逆加成裂解链转移自由基聚合的方法（RAFT）合成出一系列吡咯烷酮类嵌段共聚物聚甲基丙烯酸十二脂-嵌段-聚N-（2-甲基丙烯酰氧乙基）吡咯烷酮（PLMA-b-PNMP）,研究PLMA-b-PNMP在正构十二烷中的聚集行为。结果表明,通过调控嵌段比以改变聚合物的亲水亲油平衡,我们可以制备出球形胶束,蠕虫状胶束以及囊泡。更多还原

【Abstract】 It is well-known that self-assembly of AB diblock copolymers occurs in appropriate selective solvents, including water, n-alkanes, lower alcohols, and so forth. In this work, we have synthesized a serious of pyrrolidone block copolymer poly(lauryl methacrylate)-poly(N-(2-methacryloylxyethyl) pyrrolidone)(PMMA-b-PNMP) via reversible addition-fragmentation chain transfer(RAFT) polymerization and studied their aggregation behavior in n-dodecane. Spherical micelles, worm-like micelles, and vesicles are formed and can be related to the PLMA-PNMP diblock copolymer block lengths.更多还原
