研究了由二过碘酸合铜(Ⅲ)钾(简称Cu(Ⅲ))与可溶性淀粉组成的氧 化还原体系,于碱性介质中引发淀粉的接枝共聚合反应,得到高接枝效率的接枝共聚物,测 定了引发剂浓度、单体浓度和反应温度对接枝参数的影响,探讨了引发机理.
The graft copolymerization of soluble starch was carried out using potassium diperiodatocuprate(Ⅲ) as the initiator in alkaline medium. It wa s found that Cu(Ⅲ)-starch system was an efficient redox initiator for the graf t copolymerization. The effect of initiator concentration, monomer concentration , reaction temperature on graft copolymerization was investigated. IR and therma lanalysis have determined the structure of the graft copolymer.
