【摘要】 氧化降解的玉米淀粉与丙烯酸 (AA)、丙烯腈 (AN)和丙烯酰胺 (AM )在引发剂 (NH4) 2 S2 O8作用下进行了接枝共聚合反应 ,制得改性淀粉复鞣剂。研究了单体浓度及配比、引发剂浓度等因素对接枝共聚合反应的接枝率、单体转化率、接枝效率等的影响 ,用红外光谱对接枝共聚物的结构进行了分析表征 ,同时进行了应用实验更多还原

【Abstract】 Using (NH 4) 2S 2O 8 initiation system, the modified starch retanning agent was synthesized by the graft copolymerization of oxidizing degradation starch with acrylic acid (AA), and acryamide(AM). The effect of the starch and monomer ratio, initiator concentration on the percentage of graft, the graft efficiency, the monomer conversion were investigated. The structure of the graft copolymer was characterized by FTIR. The application test was carried out on the goatskin leather.更多还原
