用自制酯化大单体甲氧基聚乙二醇衣康酸单酯，与马来酸酐、2-丙酰胺-2甲基丙磺酸在水溶液中共聚反应合成了含有羧基、酯基和聚氧乙烯基侧链的新型聚羧酸盐减水剂。结果表明，该新型减水剂因多引入了一个羧基，增大了羧基密度，减水率和保塌性均得到了提高。在掺量为1%，初始水泥净浆流动度为280 mm，初始塌落度达到220 mm，混凝土的抗压强度得到提高。

With homemade esterification monomer IMPEG, MA and AMPS in aqueous solution copolymerization reaction in the synthesis of the containing carboxyl, ester and polyoxyethylene side chains of new type polycarboxylate superplasticizer. Results show that the new type of superplasticizer are introduced for more than a carboxyl, increases the density of carboxyl, water reducing rate and collapse are improved. The content is 1%, the initial fluidity of cement paste is 280 mm, the initial slump of 220 mm, the compressive strength of concrete was improved.
