This article reports a new kind of copolymer, non polar polar terpolymer : poly(styrene-butadiene-methyl methacrylate ) (P(S-b-B-b-MMA)) prepared by anionic polymerization with n BuLi as initiator, 1,1 diphenylethylene (DPE) as capping agent and lithium 2-(-methoxyethoxy) ethoxide (LiOEEM) as complex agent. The polymerization was in a combined solution of cyclohexane and tetrahydrofuran(THF). The temperature of the polymerization ranged from -70 ℃ to -40 ℃. The st ructure morphology properties were studied through GPC, 1H-NMR ,DSC ,TEM and IR. The result s indicated that the copolymer P(S-B-MMA) has narrow molecular weight dist ribution (MWD < 113) and the character of microphase2separation.
