    • Disclosed is a process for the synthesizing of polysilsesquioxane, including a first step for the hydrolysis, in the presence of ether, of trichlorosilane with the general formula RSiCl.sub.3 where R represents an organic radical, notably an alkyl, an aryl, a vinyl or an allyl, said process further including the following steps;2nd step: the dissolving of the solid product obtained at the end of the first step in an anhydrous ketonic solvent and the addition of a base, the reaction taking place under heat, a solid product being obtained after evaporation and drying;3rd step: the dissolving of the solid product obtained at the end of the second step in an anyhydrous ketone, the addition of a chain-terminating agent, the reaction taking place under heat and the solution obtained being filtered, evaporated and dried to give the desired polysilsesquioxane,wherein the second step is repeated several times.
    • 公开了一种合成聚倍半硅氧烷的方法,包括在醚存在下水解具有通式RSiCl 3的三氯硅烷的第一步骤,其中R表示有机基团,特别是烷基,芳基,乙烯基或烯丙基 所述方法还包括以下步骤: 第二步:将第一步末期得到的固体产物溶解在无水酮溶剂中,加入碱,反应在加热下进行,蒸发和干燥后得到固体产物; 第三步:将在第二步结束时得到的固体产物溶于无水酮中,加入链终止剂,反应在加热下进行,将得到的溶液过滤,蒸发并干燥,得到 所需的聚倍半硅氧烷,其中第二步重复数次。
