ABSTRACT:
Nitrile copolymers and graft copolymers containing a high proportionate amount of olefinic nitrile are stabilized against thermal color degradation by inclusion into the polymer minor amounts of a compound having the formula: ##EQU1## and/or ##EQU2## wherein X may be oxygen; an imide group, --NH--; or an N-substituted imide group, --NR-- wherein R may be an alkyl, or a phenyl alkyl group containing from 1 to 8 carbon atoms; Y may be an oxygen or a methylene group; and Z may be hydrogen or an alkyl group containing from 1 to 8 carbon atoms.
