ABSTRACT OF THE DISCLOSURE The specification relates to imido-oxamide compounds of the formula: Image wherein Z is a bivalent aliphatic or aromatic radical which together with the dicarboxylic group forms a monocyclic or polycyclic ring system, certain di- methyl sulfoxide and tertiary amide complexes and the N,N'-bis(isophthalimido)- oxamide derivative thereof. The imido-oxamide compounds are useful for pre- venting metal catalyzed oxidative degradation of polyolefins. The specificationalso relates to olefin homopolymer and copolymer composition containing such compounds and derivatives thereof and to a method for enhancing the resistance of olefin homopolymers and copolymers against metal catalysed oxidative degrad- ation by incorporating these compounds therein.
