DEFINITION

Classification: 44/392

Product polymerized through an olefinic double bond:

(under subclass 391) Compositions in which the compound containing the nitrogen and plural -C(=O)O- groups has been formed by polymerization of an olefinic double bond.

(1) Note. Olefinic double bonds are carbon to carbon double bond between acyclic carbons or alicyclic carbons.

(2) Note. An example of an ingredient provided for herein is the tripolymer of styrene, lauryl methacrylate, and N-(3-dimethylaminopropyl) methacrylamide.
