DEFINITION

Classification: 522/113

Processes of chemically modifying a solid polymer derived only from ethylenically unsaturated monomers by treating polymer with a chemical reactant; or compositions therefore:

(under subclass 1) Subject matter wherein a solid polymer derived from ethylenic monomers only is chemically modified by treating said solid polymer with a material which reacts therewith; or compositions therefore.

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

(2) Note. This subclass provides for compositionsfor use in processesprovidedfor herein.
