DEFINITION

Classification: 522/150

Processes of treating a solid polymer derived from ethylenic monomers only; or compositions therefore:

(under subclass 1) Subject matter wherein a solid polymer derived from ethylenically unsaturated monomers only is chemically modified in the absence of a material which reacts therewith; or compositions therefore.

(1) Note. See the General Summary of Subject Matter Within This Class in the class definition for the type of composition proper for this subclass.

(2) Note. See Class 520, Glossary, for a definition of the term "ethylenically unsaturated".

SEE OR SEARCH THIS CLASS, SUBCLASS:

161, for solid polymers which are chemically modified (nonwave energy step) and which are treated with wave energy subsequent to the chemical treatment are classified on the basis of the first solid polymer. An example of this would be hallucinating polyethylene with wave energy.
