DEFINITION

Classification: 524/561

Interpolymerized with diverse carboxylic acid ester:

(under subclass 560) Subject matter wherein an ester derived from an unsaturated monocarboxylic acid and a saturated alcohol is interpolymerized with a diverse carboxylic acid ester.

(1) Note. The diverse ester may be derived from an unsaturated acid and a saturated alcohol, or may be derived form a saturated carboxylic acid and an unsaturated alcohol, or the acid and alcohol may both be unsaturated.
