DEFINITION

Classification: 522/162

Processes of treating a solid polymer or SICP derived from at least one nonethylenic reactant or compositions therefore:

(under subclass 1) Subject matter wherein a solid polymer or SICP derived from at least one nonethylenic reactant is chemically modified in the absence of a material which reacts therewith, or compositions therefore.

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

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