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.Structures of these copolymers,i.e.P(St-co-CMS) and P(S-g-MMA),were confirmed by means of IR and ~1HNMR after purification.The average graft number,the average length of side chains,the graft ratio and the graft efficiency were also investigated.The results showed that the relative molecule weight distribution of P(S-g-MMA) was narrow,the number and length of grafts can be controlled,and the graft efficiency was as high as 93.7%.
