摘要：

通过原子转移自由基聚合(ATRP)制备了含环氧侧基的聚苯乙烯。首先用对羟基苯甲醛和环氧氯丙烷反应制备4-(2, 3-环氧丙氧基)苯甲醛(EBD),然后通过Wittig反应将醛基转化为乙烯基得到含环氧基团的功能性单体苯乙烯基环氧丙基醚 (SGE),最后用ATRP方法聚合单体SGE得到含环氧侧基的聚苯乙烯。所得聚合物分子量可控,分子量分布较窄。

关键词: 原子转移自由基聚合;环氧侧基;Wittig反应

Abstract:

Polystyrenes with epoxy pendent groups were synthesized via atom transfer radical polymerization (ATRP). First, 4-(2, 3-epoxypropoxyl) benzaldehyde (EBD) was obtained by reaction of 4-hydroxy benzaldehyde and epichlorohydrin. Then, the Wittig reaction was carried out to convert EBD to styryl glycidyl ether (SGE). Finally, the polystyrenes with epoxy pendant groups were obtained by the SGE ATRP, which had controlled molecular weight and narrow molecular weight distribution.

Key words: atom transfer radical polymerization, ATRP; epoxy pendant group; Wittig reaction
