摘　　要：研究了以聚乙二醇醚接枝的不饱和酸共聚合成 Ａ Ｅ减水剂的方法及其分散性能，并对影响产物分散性能的几个因素进行了较为深入的研究，结果表明该合成方法成本低，与目前市面上的产品相比，操作简便，产品质量稳定。The synthetic method of unsaturated carboxylic acid copolymer is studied and that copolymer presented high performance for air entraining and water reducing function.The synthetic route is designed.In this route polyethylenediol derivative maleic anhydride and 2 methylacrylic acid are used as main materials.Some factors which influence the dispersion character of the copolymer are also studied.The results showed that the water reducing agent prepared by this method has good dispersion character,the cost of materials is low and the synthetic route is simple.
