ABSTRACT:
A crosslinkable silicon polymer composition is provided comprising (A) a silicon polymer containing Si--Si bonds and Si--H groups and having a Mn of 500-500,000, (B) a polyfunctional aromatic carboxylic acid allyl ester, and (C) an organic peroxide or azo compound. The composition cures into a crosslinked polysilane film which is solvent insoluble, tough, and abrasion resistant.
