摘要/Abstract

摘要： 以马来酸酐和丙烯酸为单体,过硫酸钠为引发剂,亚硫酸氢钠为还原剂,采用水溶液聚合法,合成了用作洗衣粉代磷助剂的马来酸酐-丙烯酸共聚物[m(马来酸酐):,m(丙烯酸)=1:2].引发剂和还原剂分别为单体质量的4.0%和1.9%,聚合反应温度90℃,保温1 h.产物为粘度较低的透明液体,分散性好,色泽浅,螯合力为518 mg CaCO3/g.

Abstract: With sodium persulfate as the initiator and sodium hydrosulfite as the reducer , maleic anhydride and acrylic acid were copolymerized in an aqueous solution to synthesize the tittle copolymer , which can be used as STPP substitute in laundry powder. The weight ratio of maleic anhydride to acrylic acid was 1:2. The weight percentages of the initiator and the reducer to the monomers were respectively 4.0％ and 1.9％. The polymerization was carried out 90 oC for 1h. The production was a transparent liquid with a low viscosity and at light colour. It has good dispersivity and the chelating power was 518 mg CaCO3/g.

Key words: maleic anhydride-acrylic acid copolymer, aqueous solution polymerization, initiator, reducer, STPP substitute in laundry powder
