摘要
采用自由基引发剂用3种不同的聚合方法制备了新型的含氢聚甲基硅氧烷(PHMS)/丙烯酸丁酯(BA)/羟甲基丙烯酰胺(NMA)复合聚合物乳液。详细讨论了不同聚合方法对乳液稳定性和乳胶粒子的影响,同时对聚合反应的机理、产物的结构作了考察.结果表明:通过乳液聚合,得到了PHMS/BA/NMA共聚物;单体乳液滴加法所得乳液粒径较小,乳液性能稳定,是制备PHMS/BA/NMA复合聚合物乳液较适宜的方法.
Three feeding processes: single addition of all reagents together, drip feeding of monomer emulsion and dripping of initiator in preparation of the title composite copolymer emulsion have been compared. The second process appeared to be the best one. The emulsion thus obtained has smaller particle size and better stability.
