DEFINITION

Classification: 525/474

Solid polymer derived from silicon-containing reactant:

(under subclass 50) Subject matter involving processes of mixing solid polymer derived from a silicon-containing reactant, with additional solid polymer, with specified polymer-forming ingredients, with specified intermediate condensation product, with chemical treating agent, or with ethylenic agent; processes of forming or reacting the above mixtures or products resulting from the above processes.
