| 摘 要： | 介绍了八甲基环四硅氧烷（D4）阴离子有机硅乳液的制备方法；对由D4、十二烷基苯磺酸（DBSA）、交联剂和水组成的阴离子乳液体系进行了研究，探讨了温度、乳化剂和交联剂等对聚合的影响．结果发现，以D4单体为原料、DBSA（与D4单体质量之比为10％）为乳化剂，在反应后期（即D4转化率为80％时）滴加交联剂所得乳液体系的性能较好．

| Abstract: | A method for preparation of anionic organosiloxane emulsion polymerization of octamethylcyclotetrasiloxane （D4） was introduced. The anionid emulsion polymerization of system composed by D4, DBSA （ dedecyl benzene sulfonic acid ） , cross-linking agent and water was studied. The effect of temperatures, emulsifier amounts and cross-linking agent on the polymerization efficiency was discussed. The experimental resuits showed the system that cross-linking agent had been added during the late stage of reaction was better. And the emulsion which contained 100 g D4, 10 g DBSA, 5 g cross-linking agent that was dropped at the terminal stage when the rate of conversion reached 80% was optimum. |
