(1) Ethylethoxypolysiloxanes have been prepared by a thermal reaction of ethylethoxychlorosilanes and ethyltriethoxysilane.(2) Linear ethylethoxypolysiloxanes containing from 2 to 4 silicon atoms have been prepared and characterized.(3) Certainly, a small amount of ethylethoxycyclopolysiloxanes were formed by the thermal reaction but they could not be isolated.
(1)通过乙基乙氧基
氯硅烷和乙基三乙氧基
硅烷的热反应制备了乙基乙氧基聚
硅氧烷。(2)制备并表征了含有2至4个
硅原子的直链乙基乙氧基聚
硅氧烷。(3)当然,通过热反应形成了少量的乙基乙氧基环聚
硅氧烷。但他们无法被孤立。
