DEFINITION

Classification: 526/317.1

Form carboxylic acid monomer:

(under subclass 72) Subject matter wherein the unsaturated monomer contains at least one free carboxyl group, i.e., OH.

SEE OR SEARCH THIS CLASS, SUBCLASS:

240+, for a polymer derived from an unsaturated carboxylic acid metal salt.

292.1, for a halogen-containing carboxylic acid, salt or ester thereof.

310+, for a nitrogen-containing salt of an unsaturated carboxylic acid.

319+, for a polymer having carboxylic ester groups but devoid of a free carboxylic acid group.

930, through 940, for cross-reference art collections pertaining to the subject matter of this subclass and its indents.

SEE OR SEARCH CLASS 525, Synthetic Resins or Natural Rubbers,

329.1, for polyacrylic acid produced by oxidation of acrylonitrille and in appropriate subclasses 337-388 for the process oxidation of acryionitrile; methacrylic acid produced by hydrolysis of polyalphahydroxy methacrylic acid ester.
