摘要

本工作采用,60,Coγ射线辐照法，研究了明胶与甲基丙烯酸甲酯在水溶液中接枝共聚反应。实验结果表明：接枝率和接枝效率起先随着反应时间的增加而增加。但当反应温度和反应时间超过某值时接枝率和接枝效率反而下降。接枝侧链聚甲基丙烯酸甲酯具有较高的分子量(～10,5,）。

Abstract

Radiation induced graft copolymerization of methyl methacrylate onto gelatin (by means of ,γ, irradiation) has been investigated. Grafting reaction was carried out in aqueous solution. Results of experiments showed that the grafting percentage and the efficiency of grafting increased with the increase of reaction temperature and reaction time at the first stage. But they dropped when the reaction temperature and reaction time exceeded some certain values. The molecular weight of grafted side chains in obtained copolymers was found to be as high as 10,5,.
