A well-defined graft copolymer of styrene(St) and methyl methacrylate(MMA) was synthesized by atom transfer radical polymerization with CuCl/TMEDA as catalyst and the copolymer of styrene and p-chloromethyl styrene(p-CMS) as macroinitiator,which was synthesized by copolymerization of St and p-CMS with AIBN as initiator.
通过偶氮二异丁氰(AIBN)引发苯乙烯(St)与对氯甲基苯乙烯(p-CMS)共聚,合成了二元共聚物P(St-co-CMS),在氯化亚铜/四甲基乙二胺(CuC l/TMEDA)催化下,以此二元共聚物为大分子引发剂引发甲基丙烯酸甲酯(MMA)的原子转移自由基聚合(ATRP),成功地合成了结构明晰的以聚苯乙烯为主链、聚甲基丙烯酸甲酯为支链的接枝共聚物P(S-g-MMA)。
The hyperbranched poly(p-chloromethyl styrene) was prepared by combining atom transfer radical polymerization(ATRP) and self-condensing vinyl polymerization(SCVP).
将原子转移自由基聚合(ATRP)和自缩合乙烯基聚合(SCVP)结合,以对氯甲基苯乙烯p-CMS为引发单体进行ATRP反应,得到具有高支化结构的聚对氯甲基苯乙烯PCMS。
