摘要:
以苯乙烯(St)和对氯甲基苯乙烯(CMS)经常规自由基聚合合成无规共聚物P(St-co-CMS),再与铜试剂反应合成带有双硫酯结构的聚苯乙烯大分子RAFT试剂。在聚苯乙烯大分子RAFT试剂存在下,进行甲基丙烯酸甲酯(MMA)的常规自由基聚合反应,通过RAFT聚合机理合成接枝共聚物PS-g-PMMA。考察了St与CMS的配比、MMA用量和反应温度对接枝共聚反应的影响。研究结果表明,St与CMS的物质的量比为10:1、MMA与CMS的物质的量比为80:1,在60 ℃下进行接枝聚合,可获得很高的接枝效率和接枝率,分别可以达到60%和75%,而且接枝共聚物的分子量分布相对较窄(-2.1)。
Abstract:
Random copolymer poly(styrene-co-chloromethyl styrene)was synthesized by conventional free radical polymerization of styrene(St)andchloromethyl styrene(CMS). The polystyrene macromolecular RAFT agent with the structure of dithioester was prepared through the reaction of the random copolymerwith copper reagent. In the presence of the polystyrene macromolecule RAFT agent, radical polymerization of methyl methacrylate(MMA)was carried out and the graft copolymer poly(styrene)-g-poly(methyl methacrylate)via RAFT polymerization was prepared. The effects of the ratio of St to CMS, the contents of the MMA monomer and the reaction temperature on the graft copolymer were investigated. The results show that, graft copolymer with higher grafting ratio(-75%)and grafting efficiency(-60%)is obtained when the ratio of St to CMS is 10:1, the ratio of MMA to CMS is 80:1 and the reaction temperature is 60 ℃.
