摘要
通过采用紫外光和铈盐两种引发方式进行羟丙基纤维素与甲基丙烯酸甲酯的接枝共聚反应 ,以改善产品粘度性能 .考察了反应时间、温度、单体浓度、光敏剂或引发剂用量等对产物粘度的影响 .比较了两种引发方式的优劣 ,得出了反应的最佳操作条件 .
Gaft copolymerization on hydroxypropyl cellulose with perspex initia ted by UVlight or ammonium ceric nitrate is studied. The two methods were compared. The effect of monomer concentration , reaction time, reaction tempera ture, initiator amount or photosensitizer amount on viscosity of reaction produc ts are discussed. The optimum technological conditions are obtained.
