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。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.
