马来酸-丙烯酸共聚低温皂洗剂的合成

摘要

Maleic acid and acrylic were chosen as synthesis monomer, and polymerization method was employed to synthetic maleate-acrylic copolymer. The influences on intrinsic viscosity, chelating ability, dispersing power and solids content of synthetic polymers were investigated through single variable factor method. The optimized synthesis process is that the reaction takes place under 80~90℃for 3.5 h with 6.67%initiator dosage, monomer ratio of MA∶AA=1∶3.5, and dropping time of 2.5 h.%选用马来酸和丙烯酸为合成单体，采用水溶液聚合方法合成马-丙高分子聚合物，并通过单因素变量分析法讨论合成各因素对高分子聚合物的特性粘度、螯合力、分散力以及含固量等性能的影响，讨论分析数据，优化出最佳合成工艺：合成单体配比为n(MA)∶n(AA)=1∶3.5，反应温度为80~90℃，滴加时间为2.5 h，引发剂用量为6.67%，反应保温时间为3.5 h。
