【摘要】 以水为溶剂,过硫酸铵 亚硫酸钠为引发剂,研究了淀粉 丙烯酸 (AA) 醋酸乙烯酯 (VAc)接枝共聚反应。探讨了单体配比、引发剂用量、反应温度、反应时间等因素对反应的影响,并通过红外光谱对接枝共聚物进行了结构表征。更多还原

【Abstract】 Grafted copolymer of starch-acrylic acid-vinyl acetate was synthesized with water as solvent and ammonium persulfate-sodium sulfite as redox initiator. Result showed that temperature, concentration of initiator and the ratio of starch-acrylic acid-vinyl acetate affected conversion and graft ratio of the polymerization greatly. The grafted copolymer was further characterized by FTIR.更多还原
