摘要
以丙烯酰胺(AM)、2-丙烯酰胺基-2-甲基丙磺酸(AMPS)和苯乙烯磺酸钠(SSS)为原料,采用氧化还原和偶氮复合引发体系,在水溶液中进行自由基聚合反应,制得磺化聚丙烯酰胺(SPAM)即三元共聚物AM/AMPS/SSS。结果表明:SPAM最佳合成条件为单体质量分数10%,SSS质量分数0.5%,引发剂质量分数0.06%,氧化还原引发剂与偶氮引发剂质量比为1∶4,pH值为9,聚合起始反应温度5℃,在该条件下制得的SPAM的相对分子质量7.36×106,其耐温抗盐性能明显优于工业部分水解聚丙烯酰胺。
The sulfonated polyacrylamide （SPAM） is synthesized from acrylamide （AM）,2-acrylamide-2-methyl propane sulfonic （AMPS） and sodium styrene sulfonate（SSS） by a new co-initiator system which is composed of redox initiator and water-soluble azo initiator.The results show that the optimal synthesis conditions of AM/AMPS/SSS are as follows：monomers mass concentration is 10％,SSS amount is 0.5％,initiator mass concentration is 0.06％,mass ratio of redox to AIBA initiators is 1∶4,pH=9,reaction temperature is 5 ℃.Under this condition,the molecular weight of SPAM is 7.36 million.It has much better high temperature resistance and salt resistance than industrial partially hydrolyzed polyacrylamide.
