ABSTRACT:
Novel methods for the preparation of polymers useful as precursors to ceramic materials by catalytic activation of Si--H bonds are disclosed. The methods comprise reacting, in the presence of a catalyst effective to activate Si--H bonds, Si--N bonds, or both, and/or a reactive solvent, a polymer in the form of a polysilane, polysilazane, polysiloxane or polycarbosilane with a reactant having the structural formula R--X--H, wherein X is NR' or O, R is H, organic, silyl, siloxyl, silazanyl or carbosilyl and may contain at least one additional X--H group, and R' is H, amino, silyl or silazanyl, to produce a modified polymer containing at least one Si--X bond. Polymers produced by these methods are also disclosed.
