ABSTRACT:
Propylene-based, normally solid polymer compositions are stabilized against oxidative degradation especially when exposed to both a metal such as copper and a soft hydrocarbon medium such as petrolatum. Highly synergistic levels of stability are achieved by combining in said polymer compositions three different stabilizer additives (a), (b) and (c) as follows:
