明胶/乙烯基吡咯烷酮接枝共聚反应的研究

摘要本文研究了在水介质中以偶氮二异丁腈为引发剂的水溶性单体乙烯基吡喀烷酮与明胶的接枝共聚反应。结果表明反应温度,单体浓度,引发剂浓度,明胶浓度以及反应介质对接枝反应均有显著的影响。改变这些条件可有效地控制接枝率、接枝效率、侧链分子量以及接枝共聚反应速率。

Abstract： The graft-copolymerization of N-vinylpyrrolidone onto gelatin, with α, α′-azobisisobutyronitrile as initiator in aqueous medium has been studied. The grafting products has been verified by IR spectrum. The effeets of various reaction parameters on the percentage of grofting, grafting efficiency, average molecular weight of the grafted chains and the rate of graft copolymerization have been studied.
