摘　　要：研究了以烯丙基聚乙二醇甲基醚和低含氢硅油为原料,甲苯为溶剂,自制的催化剂,制备Si-C型聚醚改性聚硅氧烷,较适宜的合成条件为:选择相对分子量为1 000的聚醚,n(硅氢键)∶n(聚醚)=1∶1.2,反应温度90℃,催化剂用量为30×10-6,甲苯用量为总反应体系质量的25%。合成的聚醚改性硅油透明,性能优越,使用范围较广。In this study, polyether-modified siloxane was synthesized by hydrosilation of polyhydrosiloxane and allyl-polyether （APE）, using catalyst and toluene as solvent. The optimum reaction conditions were also obtained ： the molecular weight of APE is 1 000, the molar ratio of Si-H band to APE is 1 ： 1.2, reaction temperature is 90 ℃ ,amount of catalyst is 30 ×10^-6, and the concentration of solvent is 25%. The polyether modified siloxane is transparent, and has superior performance. It can be used at a wider ranges.
