DEFINITION

Classification: 525/32.1

Polymer derived from polycarboxylic acid and polyhydroxyl compound is derived from at least one polycarboxylic acid reactant which is a dimer or trimer of an ethylenically unsaturated aliphatic monocarboxylic acid having at least ten carbon atoms; or adducts of said unsaturated monocarboxylic acid with an alpha, beta ethylenically unsaturated carboxylic acid or derivative:

(under subclass 10) Subject matter wherein at least a portion of the polycarboxylic acid or anhydride is (a) a dimer or trimer of an ethylenic unsaturated aliphatic monocarboxylic acid having at least ten carbon atoms, or (b) adducts of said unsaturated monocarboxylic acid with an alpha, beta ethylenically unsaturated carboxylic acid or derivative.

SEE OR SEARCH THIS CLASS, SUBCLASS:

168+, for a system under Class 525, subclass 50 wherein the ethylenic group containing polycarboxylic acid or derivative is a dimer or trimer of an ethylenically unsaturated monocarboxylic acid having at least ten carbon atoms since these dimers and trimers are assumed to be ethylenically unsaturated materials unless otherwise specifically described as saturated or hydrogenated so as to substantially remove all residual unsaturation.
