DEFINITION

Classification: 524/502

At least one solid polymer derived from ethylenic reactants only:

(under subclass 500) Subject matter which involves the mixing of a nonreactant material with a solid polymer derived from ethylenic reactants only.

(1) Note. A chemically modified ethylenic polymer, e.g., halogenated butadiene, etc., is considered as being proper herein in that initially a solid polymer from only ethylenic reactants is present. No weight for purposes of classification herein has been given to polymers which have been treated chemically to introduce atoms or to remove atoms which were part of the original polymer derived from ethylenic monomers.
