DEFINITION

Classification: 525/55

At least one solid polymer derived from ethylenic reactants only:

(under subclass 50) Subject matter which involves mixing of a solid polymer derived from ethylenic reactants only with (a) a solid polymer, (b) specified polymer-forming ingredients or a specified intermediate condensation product, or (c) a chemical treating agent or an ethylenic reactant; or processes of reacting or the product formed by any of the mixing operations or any of the reacting processes.
