硅油乳液的研究

Research of a Silicone Emulsion

硅油乳液的研究已有报道,本文确定有机硅单体乳液聚合的反应期,提出加接种乳液缩短反应时间的聚合方法,探讨影响乳液聚合和乳液稳定性的因素。 (一)实验部分 1.硅油乳液的合成 (1)硅油乳液A:1g聚氧乙烯烷基酚硫酸氢酯,84g水,35g八甲基环四硅氧烷(D_(4))和5g接种乳液A(同样条件经50小时聚合所得乳液),45℃以300rpm搅拌聚合41小时,用10%碳酸钠中和到pH7.0,测定D4转化率和数均分子量.

Reactive periods were determined for emulsifying polymerization of D_(4);put forward a emulsifying polymerization method about to add a initiating emulsion and the effect for every factors on the emulsifying polymerization and stabilization of the emulsion was discussed.
