ABSTRACT:
The present invention describes a novel method for crosslinking polysilazane polymers having Si--H or N--H bonds. The method comprises mixing the polysilazane with a silazane crosslinker having at least 2 boron functional groups which can react with the Si--H or N--H bonds of the polysilazane and then facilitating crosslinking.
