丙烯酸氨烷基酯共聚物功能膜研制（Ⅰ）

STUDY OF FUNCTIONAL MEMBRANES OF ALKYLAMINOALKYL ACRYLATE COPOLYMERS(Ⅰ)

本文合成了甲基丙烯酸二甲胺基乙酯（ＤＭ），采用水溶液沉淀聚合法制备甲基丙烯酸二甲胺基乙酯——丙烯腈共聚物；探讨了甲基丙烯酸二甲胺基乙脂与丙烯腈（ＡＮ）共聚时，引发剂种类及用量、单体加料方式、聚合反应温度、无机酸等对聚合反应的影响，为制备甲基丙烯酸二甲胺基乙酯——丙烯腈共聚物提供了可行、实用的工艺路线。对合成的产物用红外光谱进行了定性表征。

Functional copolymers of N,N-dimethylaminoethyl methacrylate (DM) with acrylonitrile (AN) were prepared through aqueous polymerization in this study. Effects of various factors such as kinds and dosage of initiator, feeding monomer method, reaction temperature, inorganic acid (pH regulator) on the polymernization were studied. The results provided a feasible and practical technique for the production of DM-AN copolymers.
