丙烯酸乙酯与马铃薯淀粉接枝共聚

Study on graft copolymerization of acrylic ethyl onto potato starch

本实验用过硫酸钠作引发剂,对影响丙烯酸乙酯与马铃薯淀粉的接枝共聚反应的几个主要因素进行了较详细地测试比较.实验结果表明丙烯酸乙酯浓度为0.56 mol/L,引发剂浓度为5.83 mmol/L,反应温度为48℃,反应时间在120 min为最佳反应条件.

This paper studied several factors influencing graft copolymerization of ethyl acrylate onto potato starch,with sodium persulfate as initiator.The results show that the optimal concentration of ethyl acrylate and that of the initiator are 0.56mol/L and 5.83mmol/L respectively,the best temperature for reaction is 48℃,and the time of reaction is 120min.
