摘　　要：文中详细阐述了如何采用丙烯酸羟丙酯和重合抑制剂进行聚合反应,聚合级丙烯酸、封端酰铵、甲基烯丙基聚氧乙烯醚,甲基丙烯酸羟丙基磺酸钠,在引发剂过硫酸铵的作用下进行共聚合成一种聚羧酸缓释型保坍剂。分析了酸醚比、引发剂的用量、聚合的温度、反应时间等因素对聚合反应合成的影响,研究了净浆检测和混凝土性能对比等检测试验。This paper describes in detail how to use hydroxypropyl acrylate and reclosing inhibitor to carry out the polymerization reaction, polymerizing grade acrylic acid, capped ammonium, Methylallyl polyoxyethylene ether, sodium hydroxypropyl methacrylate sulfonate, under the action of the initiator ammonium persulfate, copolymerize to synthesize a polycarboxylic acid slow-release slump agent. The influences of the ratio of acid to ether, the amount of initiator, the temperature and time of polymerization on the synthesis of polymerization were analyzed.
