摘要
选择含羧酸基烯烃单体和含磺酸基烯烃单体进行共聚,在分子结构中引入羧基、磺酸基阴离子表面活性基团,该共聚物不仅具有很高的减水率(大于30% ),而且同时具有高保坍性能。
Monomer olefin containing carboxylic acid and monomer olefin containing sulfonic acid were selected to be copolymerized. Anioic surfactant with groups of carboxylic acid and sulfonic acid were introduced onto the copolumer’s chains. This copolymer not only has very high water reducing rate, but also good slump loss resistant property in concrete.
