DEFINITION

Classification: 525/416

Solid polymer derived from hydrocarbon or halogenated hydrocarbon as sole reactant or mixture thereof:

(under subclass 50) Subject matter involves processes of mixing solid polymer derived from only hydrocarbons or halogenated hydrocarbon reactants or mixtures thereof with additional solid polymer, with specified polymer-forming ingredients, with specified intermediate condensation product, with chemical treating agent, or with ethylenic agent; processes or products resulting from the above mixing processes.

(1) Note. This subclass provides for a solid copolymer derived from hydrocarbons and halogenated hydrocarbons (e.g., dichlorobenzene-xylene copolymers, etc.) or for solid polymers derived from only hydrocarbons or halogenated hydrocarbons.
