ABSTRACT:
A composition comprising a rubbery copolymer of propylene oxide in admixture with a heat age resisting mixture of a nickel dialkyl dithiocarbamate and an imidazole where the ratio of the carbamate units to imidazole units is in the range of from about 16:1 to about 1:40. The composition has particular utility for providing a rubbery copolymer of propylene oxide having improved resistance to heat aging in a temperature range of about 100.degree.C. to about 170.degree.C.
