DEFINITION

Classification: 524/235

At least one solid polymer derived from nitrile-containing ethylenic reactant:

(under subclass 233) Subject matter wherein the nitrogen compound is mixed with at least one solid polymer derived from ethylenic reactants only and at least one of the ethylenic reactants contains a nitrile group, i.e., C-C=N.
