| 摘 要： | 以马来酸酐（MA）、丙烯酸（AA）、丙烯酸甲酯（MAC）为原料，以过硫酸铵为引发剂，在水相中进行聚合反应，制备了MA／AA／MAC三元共聚物阻垢剂。通过正交实验确定了共聚反应的最佳反应条件：m（MA）：m（AA）：m（MAC）=1：0．4：0．6、引发剂用量（以单体总质量计）14％、反应温度90℃、反应时间4h。对合成的MA／AA／MAC三元共聚物进行了阻垢性能评价，结果表明：该三元共聚物对钙垢没有阻垢作用，但对硫酸钡垢阻垢效果优异。当制备的三元共聚物阻垢剂加量为60mg／L时，对标准浓度为370mg／L的硫酸钡阻垢率达97．23％。

| Abstract: | A scale inhibitor of acrylic polymer, MA/AA/MAC terpolymer, was synthesized from malefic anhydride （ MA）, acrylic acid （ AA）, and methyl acrylate （MAC） using ammonium persulfate as initiator in water phase. The optimum reaction conditions were determined by orthogonal test, that were as follows： m（MA） ： m（AA） ： m（MAC） = 1 ： 0.4： 0.6, mass ratio of the initiator to the total monomers 14%, reaction temperature 90 ℃, and reaction time 4 h. The evaluation of the scale inhibition performance of the terpolymer was carried out and the results showed that the terpolymer couldn＇ t inhibit Ca^2＋ scale, but could be an excellent scale inhibitor for BaSO4. When the amount of MA/AA/MAC terpolymer was 60 mg/L, the scale inhibiting ratio was up to 97.23% for BASO4（370 mg/L）. |
