摘要
described is a method of producing a methylpolysilans with a carbon content, which consists of a mixture of at least one alkoxyfunktionellen disilan, the disilanen with two, three and four alkoxygruppen, which siliciumatome are bound, and gemis chen this is selected, with either a alkoxyfunktionellen silan,the at least one unsaturated substituents in or with an unsaturated kohlenwasserstoffverbindung in a to increase the carbon content of the polymer is heated sufficient quantity. the implementation is carried out in the presence of a catalyst, a source of alkoxidionen.this methylpolysilanpolymeren obtained by pyrolysis in ceramic masses with increased carbon content can be transferred. these ceramics are as films, coatings and fibers and for many other purposes, for which siliciumcarbidkeramiken already used.
