【摘要】 按照一般的合成方法,以过硫酸铵或硝酸铈铵为引发剂进行直链淀粉与丙烯酰胺的共聚反应。产物的碘显色分光光度法测试结果表明,丙烯酰胺并没有在淀粉分子的长链上发生非常显著的接枝共聚反应,产物大部分是由淀粉与丙烯酰胺均聚物所形成的共混物,淀粉开环的接枝机理不成立。更多还原

【Abstract】 In accordance with the general synthetic method,the copolymerization of starch and acrylamide may be triggered by ammonium peroxydisulfate or by ammonium ceric nitrate.The iodine starch test of reaction product indicates that very significant graft copolymerization did not happen.The polyacrylamide was not linked on the long chain of starch molecules.A large number of products are not the copolymer.They are a mixture of starch and polyacrylamide.It is not established that the mechanism for opening the starch sugar ring initiating the grafting copolymerization.更多还原
