Abstract
Abstract : We have examined the polymerization kinetics of transition metal dehydrocoupling of the Si-H and N-H bonds of oligomers of the type HNMe-(H2SiNMe)x-H by size exclusion chromatography and correlated molecular weight changes with changes in shear viscosity. Analysis using simplified statistical theory that branching is a mechanism for polymerization and lends to gelation. Keywords: Polysilazanes; Preceramic polymers, Bond activation catalysis; Silanes, Ammonia; Polymerization kinetics, Silicon , Hydrogen.
