摘　　要：本文采用丙烯酸(AA)、马来酸酐(MA)、丙烯磺酸钠(SAS)为原料,通过考察物料比例、引发剂、催化剂对共聚物极限粘数与其分散性能的影响。结果表明,AA-MA-SAS的摩尔比为3.1∶1∶0.4,聚合温度85~89℃,H2O2(30%)用量为原料重量的20%,异丙醇用量为原料重量的6%,共聚物阻垢分散性能最佳,达到有机膦及市售同类型聚合物的水平,可将其作为替代无磷产品使用。The copolymer of acrylic acid(AA)-maleic anhydride(MA)-sodium propylene sulfonate(SAS) was synthesized with H2O2as initiator and isopropyl alcohol as chain transfer.The molar ratio,initiator,chain transfer were discussed.The results showed that the molar ratio of AA-MA-SAS was 3.1∶1∶0.4,the polymerization temperature was 85~89℃,the amount of H2O2(30%)was 20%,and isopropyl alcohol was 6%,the copolymer had the best scale inhibition and dispersion performance,which reached the level of organic phosphine and the same type of polymer on the market.The AA-MA-SAS copolymer could be used as a free phosphorus product.
