DEFINITION

Classification: 525/100

With saturated Si-C or Si-H reactant or polymer thereof; or with solid copolymer derived from at least one Si-C or Si-H reactant wherein at least one of the reactants forming the solid copolymer is saturated; or with specified polymer-forming ingredients wherein at least one of the necessary ingredients contains a Si-C or Si-H bond or with a reaction product thereof; or with a specified intermediate condensation product containing a Si-H or Si-C bond:

(under subclass 55) Subject matter wherein, in addition to the solid polymer derived from ethylenic reactants only, there is additionally present (a) a saturated reactant containing a Si-C or Si-H bond or a polymer thereof, or (b) a solid copolymer derived from a Si-C or Si-H-containing reactant wherein at least one of the reactants forming the solid copolymer is saturated, or (c) specified polymer-forming ingredients wherein at least one of the necessary polymer-forming ingredients contains an Si-C or Si-H bond and at least one of the necessary polymer forming ingredients is saturated or a reaction product thereof, or (d) a specified intermediate condensation product containing an Si-C or Si-H bond.
