摘要: 通过丙烯酸和甲氧基聚乙二醇的酯化,生成了一种具有反应活性的聚羧酸类减水剂中间大分子单体——甲氧基聚乙二醇丙烯酸酯。探讨了各种实验条件对酯化反应的影响,得出了合成甲氧基聚乙二醇丙烯酸酯的最佳工艺条件。

Abstract: A kind of monomer with reaction activity,methoxypolyethylene glycol acrylate,which could be used as the intermediate macromonomer of polycarboxylate high performance water-reducer,was prepared by the esterification of acrylic acid and methoxypolyethylene glycol. The experimental conditions were investigated,and the optimum conditions for preparing methoxypolyethylene glycol acrylate were determined.
