摘要：

用水作溶剂，（NH₄）₂S₂O₈/NaHSO₃氧化还原体系作为引发剂，以2-丙烯酰胺基-2-甲基丙烷磺酸（AMPS）、马来酸酐（MA）为单体，与自制的聚乙二醇-衣康酸酯通过溶液聚合制备了一种新型磺酸基聚合物阻垢剂。用红外光谱和热分析方法对聚合物进行了表征和分析。探讨了单体配比、引发剂用量、反应温度对聚合物阻垢性能的影响。结果表明，该共聚物对于碳酸钙盐具有优异的阻垢效果。阻垢剂用量为15 mg/L时，对碳酸钙的阻垢率可达到95%以上。

Abstract:

A new sulfonate copolymer scale inhibitor was prepared by solution polymerization of polyethylene glycol - itaconic acid ester and 2-acrylamido-2-methyl propane sulfonic acid（AMPS）and maleic anhydride（MA）as monomers，with water as solvent，and (NH₄)₂S₂O₈/NaHSO₃ as initiator. The macromolecular polymer was characterized with IR and TG-DTA. The effects of monomer ratio，initiator dosage，reaction temperature on the copolymer’s antiscaling performance were investigated. The experimental results showed that the copolymer was an excellent inhibitor against deposition of CaCO₃. The inhibition efficiency of CaCO₃ could reach 95% when the dosage of the terpolymer was 15mg·L^-1.
