摘　　要：以低浓度丙烯酸溶液、甲基丙烯酸甲酯为原料,合成了丙烯酸共聚物,最佳工艺条件为:丙烯酸与甲基丙烯酸甲酯的摩尔比为5∶1,引发剂用量为单体总重的2%,分子量调节剂用量为9.5%,反应温度为70℃,反应时间为3 h。共聚物的阻CaCO3垢率达87.21%。Low concentration acrylic acid, methyl methacrylate was synthesized to acrylic copolymer. The optimum process conditions were as follows：the mole ratio of acrylic to methyl methacrylate was 5： 1, the initiator dosage was 2% of the total weight of monomer, the molecular weight regulator dosage was 9.5 % , reaction temperature was 70 ℃, reaction time was 3 h. The eopolymer blocking CaCO3 scaling rate was 87.21%.
