METHOD OF FORMING POLYSILANES AND POLYCARBOSILANES IN THE PRESENCE OF A METAL SILICIDE

A mixture of at least one polysilane and at least one polycarbosilane is formed in the presence of a metal silicide. The mixture is formed utilizing a method that includes the step of combining the metal silicide and an alkyl halide in a reactor at a temperature of from 200° C. to 600° C. The alkyl...

Zusammenfassung:	A mixture of at least one polysilane and at least one polycarbosilane is formed in the presence of a metal silicide. The mixture is formed utilizing a method that includes the step of combining the metal silicide and an alkyl halide in a reactor at a temperature of from 200° C. to 600° C. The alkyl halide has the formula RX, wherein R is C1-C10 alkyl and X is halo. This method forms high yield mixtures of the at least one polysilane and the at least one polycarbosilane. Additionally, the mixture is time and cost effective and allows the mixture to be formed in a predictable and controlled manner. Moreover, the components used in this method can be easily recycled and/or re-used in other processes.
