DEFINITION

Classification: 523/411

Polymer derived from ethylenic reactants only derived from reactant-containing nitrogen:

(under subclass 409) Subject matter wherein the polymer derived from ethylenic reactants only is derived from a nitrogen-containing reactant.

(1) Note. The nitrogen atom may be in the same reactant as the chalcogen atom or may be in a separate nitrogen, nonchalcogen-containing reactant which is copolymerized with a chalcogen-containing reactant.
