摘要
淀粉—丙烯腈的接枝共聚反应,通常是在含铈的催化体系存在下进行的。笔者经过研究提出一种廉价的不含铈离子的催化体系(UC)也得到了良好的接枝共聚物.本文讨论了催化剂(UC)的浓度、温度、反应时间等对接枝反应的影响.
The graft copolymerization of starch with acrylonitrile are carried out usually in the presence of catalyst systems containing cerium.This paper presented a cheap catalyst(VC)which contains no ceric ion but also can get an excellent graft copolymer.The influence of concentration,temperature and time of reaction of the catalyst on the graft copolymerization was discussed in this paper.
