阳离子乳液聚合制备聚硅氧烷微乳液研究

Study of Preparation of Polysiloxane Microemulsion by Cationic Emulsion Polymerization

以八甲基环四硅氧烷(D4)为反应原料,十六烷基三甲基氯化铵为乳化剂,氢氧化钾为催化剂,脂肪醇聚氧乙烯醚为助乳化剂,通过阳离子乳液聚合反应,合成了均匀细腻、略泛蓝光的透明聚硅氧烷微乳液,乳液具有优异的稳定性。

The cationic polymerization of cyclosiloxane in aqueous emulsion was perfected with octamethylcyclotetrasiloxane（D4） as monomer,hexadecyl trimethyl ammonium Chloride（CTAC）） as cationic emulsifying agent,KOH as catalyst and fatty alcohol polyoxyethylene ether（AEO-6,AEO-9） for auxiliary emulsifie.Uniform fine,slightly and generic blue-ray transparent microemulsion was prepared,which has excellent stable performance.
