【摘要】 研究了以高锰酸钾为引发剂,加入纤维素的淀粉-丙烯酰胺接枝共聚反应。考察了淀粉与纤维素的配比、引发剂用量、单体浓度、介质 pH 值、反应温度、反应时间对接枝反应的影响。并讨论了纤维素促进淀粉-丙烯酰胺接枝共聚反应的机理。更多还原

【Abstract】 The graft copolymerization of acrylamide with starch in the presence of cellulose by KMnO₄ initiation has been stud- ied.The influence of the ratio of cellulose to starch,amount of initiator,amount of monomer,pH value,reaction tem- perature,reaction time etc.on the graft copolymerization were investigated.The mechanism about this graft copolymer- ization were discussed also.更多还原
