DEFINITION

Classification: 522/165

Solid polymer or SICP derived from polycarboxylic acid or derivative and polyol:

(under subclass 162) Subject matter wherein the solid polymer

or SICP modified is formed from at least two reactants, at least one of which is a polycarboxylic acid or derivative and at least one of which is a polyol.

(1) Note. See Class 520, Glossary, for a definition of the term "carboxylic acid or derivative". The term "polycarboxylic" can also be found under the heading.

(2) Note. A polyo contains two or more C-OH groups wherein the carbon atom bonded to the oxygen of the -OH moiety is not double bonded to a chalcogen atom.
