摘　　要：研究甲基丙烯酸镁[Mg(MAA)2]对氯化聚乙烯橡胶(CM)的补强和助交联作用。结果表明,Mg(MAA)2是硫化剂DCP优异的助交联剂,其对CM的交联效果优于助交联剂TAIC。与助交联剂TAIC体系相比,Mg(MAA)2体系的储能和损耗模量均较大,损耗因子(tanδ)较小,tanδ峰值温度向低温方向移动。Mg(MAA)2体系的300%定伸应力、拉伸强度和拉断伸长率均高于助交联剂TAIC体系。Reinforcement and the co-curing effect of chlorinated polyethylene（CM）by magnesium methacrylate[Mg（MAA）2] were investigated.The results showed that,Mg（MAA）2 was a good secondary curing agent with DCP,and its curing effect on CM was better than that of the secondary curing agent TAIC.Compared with TAIC system,with Mg（MAA）2 system,the vulcanizates possessed higher storage modulus and loss modulus,and lower loss factor（tanδ）;the peak of tanδ shifted to low temperature region;the modulus at 300%,tensile strength and elongation at break were better.
