DEFINITION

Classification: 528/401

(under subclass 1) Subject matter under Class 520, ... involving polymers derived from a fluorine- containing reactant or process of polymerizing; polymerizable compositions containing as a reactant a fluorine-containing material or processes of preparing.

SEE OR SEARCH THIS CLASS, SUBCLASS:

480+, for processes of preparing a polymer not involving a chemical modification of the polymer, by the addition of a material thereto, and for chemically modifying material other than the polymer. Subclasses 480+ also provide for processes of admixing with a broadly claimed nonreactant material.
