不同引发体系下明胶的接枝改性

摘要本文系统地研究了ＡＩＢＮ，Ｈ_２Ｏ_２－ＦｅＳＯ_４，Ｋ_２Ｓ_２Ｏ_８，Ｈ_２Ｏ_２－抗坏血酸以及Ｃｅ（ＮＨ_４）２（ＮＯ_３）_６等五种引发体系对乙烯基吡咯烷酮在明胶上的接枝共聚反应。并以接枝率、接枝效率和侧链分子量为参数比较了前三种引发体系的引发效果。结果表明乙烯基吡咯烷酮与明胶的接枝共聚反应可在弱酸性水溶液中进行，在强酸性介质中单体严重水解而失去聚合能力。通过选择合适的引发体系，调整反应条件可以控制接枝共聚物的组成。

Abstract： The graft-modification of gelation with vinylpyrrolidone using different initiating systems has been studied.The results indicated that the graft copolymerization was greatly effected by the properties of initiator, the reaction temperature and the concentration of monomer.So the desired graft copolymer can be produced by choise of the appropriate reaction conditions under the suitable initiator.
