制备了一种紫外光固化预聚物--带有羧基的低分子量聚丙烯酸酯丙烯酸树脂(Polyacrylate acrylic resin, PAAR).其主链由丙烯酸烷基酯和丙烯酸进行共聚而得,当采用丙烯酸甲酯、丙烯酸乙酯和丙烯酸(摩尔比1∶1∶1)作为共聚单体,引发剂AIBN为1 5%,链转移剂十二硫醇为2 5%时,聚合得到的聚丙烯酸酯(Polyacrylate, PA)分子量在1100-1400之间,多分散性小于2,反应速率快,转化率高;由这种PA和甲基丙烯酸缩水甘油酯(GMA)进行酯化反应,制备得到最终产物聚丙烯酸酯丙烯酸树脂,酯化率可以达到80%以上,其光固化膜具有较好的涂膜硬度和柔韧性,光泽度饱满.
