摘　　要：磺化苯乙烯-马来酸酐共聚物分子中具有羧基和磺酸基,是很好的聚电解质,能够做为混凝土减水剂。而由磺化苯乙烯-马来酸酐共聚物接枝的聚氧乙烯基醚聚羧酸,分子结构中具有产生空间位阻的长支链和强的极性基团,有利于实现大减水、高保坍的高性能减水剂的要求。Carboxylate and mary sulfonate anions are involved in the molecular chain of the sulfonated copolymer of styrene-maleic anhydride which is an excellent electrolyte and can be applied as superplasticizer of concrete. The grafted polycarboxylate copolymer of SSMA-g-PEG has long steric side chains and strong polarity functional group which accords with the requirement of the high-performance superplasticizer of high water reducing and slump retain
