Abstract
The invention is concerned with novel polysilamethylenosilane polymers having polysilane-polycarbosilane skeleton which can be prepared in one-step reaction from mixtures of chlorosilaalkanes and organochlorosilanes with alkali metals in one of appropriate solvents or in combination of solvents thereof. Such polysilamethylenosilane polymers are soluble and thermoplastic, and can be pyrolyzed to obtain improved yields of silicon carbide at atmospheric pressure.
