2、酸十八酷是疏水性的则溶解在油相,致使在聚合反应中聚合不能平稳进行,得到的产品增稠能力和耐电解质能力不理想。丙烯酸和丙烯酸十八酷进行溶液聚合。丙烯酸、丙烯酸十八酷和,一亚甲基双丙烯酞胺溶解在苯中,以偶氮二异丁氰为引发剂,保持℃聚合,过滤,干燥,得到白色粉末。把粉末加入到溶有一的溶剂油中高速搅拌,滴加氨水中和,加入壬基苯基聚氧乙烯醚一转相得到白色的增稠剂。得到的产品颗粒不均匀,增稠能力差,耐电解质能力较好。丙烯酸和丙烯类单体进行反相乳液聚合。实验室自制单体的端基为磺酸基团,磺酸根离子为强酸根离子,有
3、较强的水溶性,使单体能溶于水。以过硫酸按一亚硫酸氢钠为引发剂,以,一亚甲基双丙烯酞胺为交联剂,反相聚合丙烯酸和单体,聚合完毕后减压蒸馏脱水,加入壬基苯基聚氧乙烯醚一转相得到淡黄色粘稠的增稠剂,其增稠能力和粘度系数与增稠剂相当,耐电解质能力是普通增稠剂的一倍。关键词增稠剂耐电解质丙烯酸十八醋反相乳液聚合丙烯酸汕一,州七,州,,娜,,,,,,,℃,一,,一八刀却一,,一,一,一,,一,,,一,,一一目录引言···············································
