摘　　要：优化接枝变性淀粉的制备工艺。采用正交试验方案,在不同的氧化剂浓度、还原剂浓度、丙烯酸乙酯浓度、丙烯酰胺加入量和浴比的条件下,制得不同性能的接枝变性淀粉浆料,通过对接枝率、接枝效率和单体转化率进行测试和统计分析,最终使得淀粉浆料接枝变性工艺条件得到优化。研究得出淀粉浆料接枝共聚反应的理想工艺为氧化剂浓度0.125%,还原剂浓度0.4%,浴比1∶3,丙烯酸乙酯浓度20%,丙烯酰胺浓度1.4%。Preparation processing of graft modificatiqn ＇starch was optimized. Through orhogonal test, in different concentrations of oxidant, reducer, ethyl acrylate, acrylamide, liqu6r ratio, different graft modification starch size mixtures were made. Through testing and analyzing grafting rate, grafting efficiencyj and monomer conversion rate, starch size mixture grafting modification processing conditions were optimized. The research shows that the ideal processing of starch size mixture graft copolymerization is 0. 125% oxidant concentration,0.4% reducer concentration, 1 ： 3 liquor ratio, 20% ethyl acrylate concentration and 1.4% acrylamide concentration.
