摘要：通过苯乙烯 (St)与 4 对氯甲基苯乙烯 (CMS)进行氮氧稳定自由基共聚合反应 ,合成了二元共聚物P(St co CMS) ,并以此共聚物引发丙烯酸丁酯进行原子转移自由基聚合 ,成功地合成了结构明晰的以聚苯乙烯为主链、聚丙烯酸丁酯为支链的接枝共聚物 ,研究了共聚合反应动力学 .P(St co CMS)和接枝共聚物的结构通过1 H NMR得到确认 。
A well-defined graft copolymer of styrene (St) and n-butyl acrylate (BA) was synthesized by atom transfer radical polymerization (ATRP) with the copolymer of styrene and chloromethyl stryrene as macroinitiator, which was first synthesized by the nitroxide-mediated copolymerization of St and 4-chloromethyl styrene (CMS) at 130degreesC with benzoyl peroxide/4-hydro TEMPO as initiator. The kinetics of the two kinds of 'living'/controlled polymerization were also studied. These copolymers, i.e. P(St-co-CMS) and P (St- g-BA), were characterized by means of GPC,DSC and H-1-NMR, respectively. The average graft number and length of side chains for such a kind of graft copolymer were defermined.
