摘　　要：以衣康酸(IA)、丙烯酸甲酯(MA)、丙烯酰胺(AM)和2-丙烯酰胺基-2-甲基丙磺酸(AMPS)为原料,过硫酸铵为引发剂,通过水溶液自由基聚合的方法合成了IA-MA-AM-AMPS四元共聚物阻垢剂,利用红外光谱对共聚物的结构进行了分析;探讨了单体配比、反应温度、反应时间对共聚物阻垢性能的影响,确立优化合成条件。并且通过静态法评价了其阻垢性能和分散氧化铁性能。结果表明,该四元共聚物的阻垢性能和分散氧化铁性能均优于市售阻垢剂,在共聚物质量浓度为30 mg/L时,对Ca CO3阻垢率可达98.7%。Through aqueous radical polymerization, a novel tetrapolymer scale inhibitor of IA-MA-AM-AMPS had been synthesized from the copolymerization ofitaeonic acid （IA）, methyl acrylate （MA）, acrylamide （AM） and 2-acrylamide-2-methyl propane sulfonic acid （AMPS）, using persulfate ammomium as initiator. The structure of the copolymer was analyzed by IR. The effects of monomer ratio, reaction temperature and reaction time on the performance of eopolymers scale inhibitor were discussed, and optimum synthesis conditions were established. In the static experiment method, the scale inhibition performance and the dispersed iron oxide were evaluated. The results showed that the scale inhibition performance and the dispersed iron oxide performance of synthesized tetracopolymer were better than that of other commercial copolymers. When the mass concentration of the scale inhibitor was 30 mg/L, the CaCO3 scale inhibiting rate could reach 98.7%.
