摘要： The present invention pertains to a method for producing a polysilane-polycarbosilane copolymer solution, which comprises the preparation of a polysilane, obtained by the disproportionation of a methylchlorodisilane or a mixture of methylchlorodisilanes of the formula Si2MenCl6-n with a Lewis base as the catalyst, a subsequent thermal crosslinking of the polysilane to form an infusible polysilane-polycarbosilane copolymer that is soluble in inert solvents, as well as the production of said solution by the dissolution of the polysilane-polycarbosilane copolymer in an inert solvent. In addition, the present invention also pertains to a method for producing oxygen-depleted ceramic fibers and other molded bodies having a composition similar to that of SiC. The method for producing the fibers comprises the preparation of a polysilane-polycarbosilane copolymer solution, the spinning of this solution to obtain green fibers according to the dry spinning method, as well as the pyrolysis of the dried green fibers under an inert gas atmosphere or a reducing atmosphere.

摘要： The invention relates to a method for producing a polysilane-polycarbosilane copolymer solution. Said method comprises the preparation of a polysilane, obtained by the disproportionation of a methylchlorodisilane or a mixture of methylchlorodisilanes of formula Si2MenC16-n with a Lewis base as the catalyst, a subsequent thermal cross-linking of the polysilane to form an infusible polysilane-polycarbosilane copolymer that is soluble in inert solvents, in addition to the production of said solution by the dissolution of the polysilane-polycarbosilane copolymer in an inert solvent. The invention also relates to a method for producing oxygen-depleted ceramic fibers and other molded bodies with a composition similar to that of SiC. Said method comprises the spinning of the solution to obtain green fibers according to the dry spinning method and the pyrolysis of the dried green fibers in an inert gas atmosphere or a reductive atmosphere.
