端-侧基氨基聚醚改性硅油的合成及其微乳液制备

Synthesis of silicone oil modified by amino-polyether at terminal-side position and its microemulsion

采用本体聚合法,以自制环氧封端剂、D4、3-缩水甘油丙基（二甲基）甲基硅烷为原料,四甲基氢氧化铵为催化剂,合成端-侧基环氧改性硅油,利用氨基与环氧基的氨解开环反应,将氨基聚醚引入,合成端-侧基氨基聚醚改性硅油,采用1H NMR及FT-IR证明产物合成.制备端-侧基氨基聚醚改性硅油微乳液,探讨了乳液参数对乳液平均粒径、表面张力及透光率的影响.

Silicone oil modified by epoxy at terminal and pendant position was synthesized with homemade epoxy capping agent,octamethylcyclotetrasiloxane(D_4),and 3-gylcidylpropyl(dimethyl)methylsilane as raw material,and(CH)_4NOH as catalyst.Amino-polyethers were introduced into the epoxy modified silicone oil by ringopening reaction of amidogen and epoxy group.The chemical structure of product was confirmed by ~1 H NMR and FT-IR.The amino polyether modified silicone oil was also made into microemulsion,and the effects of microemulsion parameters on average particle size,surface tension and light transmittance were investigated in detail.
