摘要
以过硫酸铵和双氧水为复合引发体系,采用不饱和单体直接共聚,得到一类主链为羧基、酯基、酰胺基,侧链为聚乙二醇醚基的新型聚羧酸高效减水剂,研究了共聚物的结构对分散性能的影响。
Based on hydrogen peroxide and ammonium persulfate as compounded initiating system, unsaturated vinyl monomers were used to directly copolymerize a new high range polycarhoxylate water reducer structurized in carhoxyl, esterquat and amido as main chain and in polyethylene glycol ether as side chain. Effects of structure of the copolymer on its dispersancy were studied.
