DEFINITION

Classification: 528/397

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

(1) Note. Included as halogenated hydro- carbons for purposes of this subclass are those reactants wherein all of the hydro-carbon atoms have been replaced by halogen atoms.
