DEFINITION

Classification: 525/420.5

Solid polymer derived from a polycarboxylic acid which is a dimer or trimer of an aliphatic acyclic monocarboxylic acid having at least ten carbon atoms or adducts of unsaturated aliphatic acyclic monocarboxylic acids, having ten carbon atoms with an alpha, beta ethylenically unsaturated carboxylic acid or derivative:

(under subclass 420) Subject matter wherein the solid polymer is derived from a polycarboxylic acid which is a dimer or trimer of an aliphatic acyclic monocarboxylic acid having at least ten carbon atoms or an adduct of an unsaturated aliphatic acyclic monocarboxylic acids, having ten carbon atoms with an alpha, beta ethylenically unsaturated carboxylic acid or derivative.

(1) Note. Hydrogenated forms of the dimer and trimer acids are included herein.

(2) Note. The solid polymer containing the dimer, trimer, or adduct polycarboxylic acid need not be the solid polymer described in this subclass.
