甲基丙烯酸甲酯-丙烯酸丁酯-丙烯酸三元溶液聚合研究 Ⅲ 聚合物性能研究

Studies on Solution Polymerization of Methyl Methacrylate-Butylacrylate-Acrylic Acid Copolymer Ⅲ Properties of Copolymer

利用溶液聚合法合成了 Poly( MMA-BA-AA) ,对影响聚合物性能的各因素进行了研究 ,得到了聚合体系溶剂种类、AA用量、单体 MMA/BA质量配比、AIBN用量、聚合温度改变时聚合物的 M——W、[η]、Tg、光泽度。

The poly (MMA-BA-AA) copolymer has been synthesized through solution polymerization. The effect of factors of copolymerization on properties of copolymer is studied. The gereral regulations was found that W??Tg. lustre and hardenss of copolymer changed when the kind of solvent, MMA/BA weight ratio, content of AA and AIBN, copolymerization temperature changed.
