聚甲基丙烯酸乙酯的合成与性能研究

Synthesis and study on the property of poly(ethyl methacrylate)

通过阴离子聚合反应合成了窄分子量分布(D =1 0 5～1 2 )聚甲基丙烯酸乙酯(PEMA)。运用IR谱、1HNMR和GPC等手段对合成产物进行了表征,探讨了影响甲基丙烯酸乙酯(EMA)阴离子聚合反应的因素,测定了该聚合物的玻璃化温度Tg。

The ploy(ethyl methacrylates)of narrow molecular weight distribution(D=1.05～1.2)were syntheszed by anionic polymerization.The products were characterized by IR,~1HNMR,and GPC.The factors affecting of anion polymerization of ethyl methacrylate were researched.And,its T_g and degradation property in different pH solution were measured.
