摘要
以甲基丙烯酸十二氟庚酯(FA)和甲基丙烯酸二甲基胺乙酯(DM)为原料,偶氮二异丁腈为引发剂,二氧六环为溶剂,在75℃反应6 h,制备了Poly(FA-co-DM),该聚合物经苄氯季铵化得到阳离子氟代丙烯酸酯共聚物QPFD,利用红外光谱、核磁共振氢谱、元素分析、热重分析、示差扫描量热、凝胶渗透色谱对其结构进行了确认和表征。研究了QPFD溶液的性质,证实该聚合物在纯水中具有表面活性。
Copolymers Poly （FA-co-DM） of dodecafluoroheptyl methacrylate （FA） and dimethylaminoethylmethacrylate （DM） were prepared by free radical polymerization in dioxane at 75 ℃ using azodisisobutyronitrile as the initiator for 6 h. The cationic copolymer QPFD was synthesized by the quaternarization reaction of Poly（FA-co-DM） with benzyl chloride. These copolymers were characterized by FTIR, ^1H- NMR, DSC, TG, GPC and elemental analysis. The solution properties of QPFD was also studied. Results indicated that QPFD had surfactivity and characteristics of polyelectrolyte.
