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 RSiCl3 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. |
