矽氧型高分子化合物在工业上已有极广泛的应用,其中甲基苯基矽氧型共缩聚物更具有特殊的性能。可是,至目前为止,共缩聚反应的规律和机构等基本问题还研究得很少。在酸性介质中,三甲基羟基矽烷比三苯基羟基矽烷的缩合速度约快一百万倍,在硷性介质中,尚无比较数字。按照一般形成矽氧型高分子化合物的方 Silicone type polymer has a very wide range of industrial applications, of which methylphenyl silica co-condensation polymer has more special properties. However, until now, the basic problems such as the rules and mechanisms of copolycondensation have not been studied yet. In acidic media, trimethylhydroxysilane condenses about a million times faster than triphenylhydroxysilane, with no comparable numbers in alkaline media. In accordance with the general formation of silicon type polymer compound side
