摘要
应用甲基丙烯酸(MAA)、对苯二酚、对苯二酚单甲醚、促进剂和MPEG合成酯化大单体,通过酯化反应工艺条件的确定,得到一种高性能的聚羧酸高效减水剂,指出该工艺研究目前已能用于实际生产,具有良好的经济价值。
A kind of intermediate macromonomer of polycarboxylate high performance water-reducer was prepared by the MAA,methacrylic acid,pdihydroxybenzene,accelerant and MPEG.The synthesis technics were investigated, and the optimum conditions for preparing methoxypolyethylene glycol acrylate were determined.It is a good technics to the practice and have good economic value.
