Methylpolysilanes and method for their preparation

Abstract From the Canadian patent

Abstract, A process for the preparation of a methylpolysilane having a controlled carbon content is provided which includes the steps of haating together to form a raaction mixture at least one alkoxy-functional disilane selected from the group consisting of disilanes having two, three and four alkoxy groups bonded to the silicon atoms, and mixtures thereof with either an alkoxy-functional silane having at least one unsaturated substituent or an unsaturated hydrocarbon compound in an amount effective to increase the carbon content of the resulting polymer. The reaction is carried out in the presence of a catalyst which is a source of alkoxide ions. The methylpolysilane polymers produced may …
