| 摘 要： | 研究了以聚乙烯醇为保护胶体的醋酸乙烯乳液聚合中，作为保护胶体的聚乙烯醇与醋酸乙烯的接枝反应。发现聚乙烯醇的接枝主要发生在初期，而醋酸乙烯的接枝链一直增长到胶粒沉析；另外，保护胶体黏度对接枝率也有影响，黏度越大醋酸乙烯的接枝率越低。

| Abstract: | The grafting reaction of vinyl acetate with polyvinyl alcohol which was regarded as the protecting colloid in the emulsion polymerization of vinyl acetate was investigated in this paper. It was found that the grafting reaction of polyvinyl alcohol was mainly happened at the beginning and the grafting chain of vinyl acetate was growing until precipitation of gel particles, the grafting ratio was effected by the viscosity of protecting colloid: the more viscosity, the less grafting ratio. |
