DEFINITION

Classification: 525/329.5

Polymer derived from carboxylic acid or derivative monomer other than: vinyl acetate; or acrylic-or methacrylic-acid, or derivatives:

(under subclass 326.1) Product wherein the solid polymer, which has been chemically modified, is obtained from an ethylenic monomer which is a carboxylic acid or derivative other than: vinyl acetate; or acrylic or methacrylic acid or derivatives.

329.7+, and 330.3+, for chemically modified solid polymers based upon derivatives of acrylic or methacrylic acid, e.g., acrylyl chloride or ethyl acrylate, etc. and subclasses 330.3+ for polymers derived from vinyl acetate.
