ABSTRACT:
A method for cross-linking organopolysilane polymers. The method includes the steps of mixing an organopolysilane with a cross-linking agent to make a reaction mixture. The cross-linking agent includes molecules having at least two carbon-carbon double bonds and a ratio of such bonds to the molecular weight of the molecule of at least 1:150. Radical formation is then induced in the organopolysilane of the reaction mixture to cause formation of a reaction product including cross-linked organopolysilane polymers.
