摘　　要：以马来酸酐(MA)、乙醇胺(EA)、衣康酸(IA)以及2-丙烯酰胺-2-甲基丙烷磺酸(AMPS)为单体,过硫酸铵和次亚磷酸钠为引发剂,采用水溶液自由基聚合制备PTA-IA-AMPS三元功能共聚物。通过正交优化和验证实验确定最佳合成条件。采用静态阻垢法和旋转挂片法分别测试合成产物的阻垢和缓蚀性能。结果表明,共聚单体的摩尔比(nIA∶nPTA∶nAMPS)为2.5∶1∶0.1、引发剂过硫酸铵和次亚磷酸钠用量分别为单体总质量的8%和20%、反应温度为90℃且反应时间4 h,合成的PTA-IA-AMPS共聚物性能最佳;用量为30 mg/L时,阻垢率可达90.83%,缓蚀率99.40%,属于抑制阴极为主的阴极型缓蚀剂,性能优良。PTA-IA-AMPS copolymer is prepared from maleic anhydride(MA),ethanolamine(EA),itaconic acid(IA)and 2-acrylamido-2-methylpropane sulfonic acid(AMPS)by free-radical polymerization in aqueous solution with ammonium persulfate and sodium hypophosphite as initiators.The structure of PTA-IA-AMPS copolymer is characterized by infrared spectrum.The optimal synthesis conditions are determined through orthogonal experiments and single factor experiments.The static scale inhibition method and rotating film method are used to test the scale and corrosion inhibition performance of the synthesized product.The results show that the scale inhibition efficiency of PTA-IA-AMPS terpolymer against calcium carbonate is 90.83%and the corrosion inhibition efficiency can reach 99.40%,when molar ratio nIA∶nPTA∶nAMPS is 2.5∶1∶0.1,the amount of initiators ammonium persulfate and sodium hypophosphite are respectively 8%and 20%of the total monomer mass,reaction temperature is 90℃,the reaction time is 4h and the amount of synthetic PTA-IA-AMPS terpolymer is 30 mg/L.
