摘要
采用乳液聚合方法合成了 PHMS/ VAc/ NMA复合乳液 ,较详细地讨论了乳液的组成结构 ,并对乳液的耐电解质稳定性、耐酸碱稳定性等性质作了研究。研究证明 ,该反应的本质是活泼氢对不饱和 C=C的自由基硅氢加成 ,同时也存在少量的均聚反应 ,复合乳液由 PHMS/ VAc/ NMA接枝共聚物与 PVAc均聚物组成 。
PHMS/VAc/NMA composite emulsion was synthesized. The structure characters of composite emulsion were studied, in detail, and the resistance to alkali, to acid, and so on was investigated. The results indicate that the reaction fact is the hydrosilicon addition reaction between active H and C=C . The composite emulsion is compose of PHMS/VAc/NMA graft copolymer and PVAc homopolymer. The properties of composite emulsion are good.
