摘　　要：以4-氯甲基苯甲酸、1,10-癸二醇、顺丁烯二酸酐为主要原料,通过三步反应合成了具有阴离子表面活性的原子转移自由基聚合(ATRP)引发剂:4-(10-(4-氯甲基苯甲酰氧基)癸氧基-4-氧代-2-磺酸基丁酸二钠(3)。第一步选择性酯化的分离产率为81%,第二步酯化的分离产率为64%,第三步最终产物的收率为91%。对合成的中间体用红外光谱、核磁共振、元素分析等进行了结构确认。利用产物3既作引发剂又作乳化剂,对甲基丙烯酸甲酯(MMA)进行水体系中的无皂乳液聚合,结果表明反应速度很快,聚合具有活性/可控特征。An anionic surface-active atom transfer radical polymerization（ATRP） initiator disodium 4-（10-（4-chloromethylbenzoxy）decoxy-4-oxo-2-sulfonatobutanoate（3） has been synthesized efficiently in three steps.81% and 64% separation yields were obtained in the first two esterification steps,respectively,and the final initiator 3 was afforded in 91% yield in the third step.The intermediates were characterized by IR,NMR and EA,respectively.Emulsifier-free emulsion polymerization of methyl methacrylate（MMA） with 3 as both an initiator and an emulsifier has been successfully performed,which featured fast reaction rate and living/controlled characterization.
