DEFINITION

Classification: 522/134

Processes of chemically modifying a solid polymer or SICP derived from a least one saturated monomer by treating solid polymer or SICP with a chemical reactant; or compositions therefore:

(under subclass 1) Subject matter wherein a solid polymer derived from at least one nonethylenically unsaturated reactant or SICP is chemically modified by treating said solid polymer or SICP with a material which reacts therewith; or compositions therefore.

(1) Note. This subclass provides for compositions for use in processes provided for herein.

(2) Note. See Class 520, Glossary, for a definition of the term "specified intermediate condensation product (SICP)".
