ABSTRACT:
An olefinic polymer composition is provided which comprises an olefinic polymer selected from homopolymers and copolymers made from aliphatic, ethylenically unsaturated monomers containing from 2 to about 10 carbon atoms; from about 100 to about 3,000 parts per million based on the weight of the total composition of a hindered phenolic stabilizer; and from about 100 to about 10,000 ppm based on the weight of the composition of a stabilizer selected from compounds of the formula: ##STR1## wherein R.sub.1 and R.sub.2 are each independently selected from an alkyl group containing from 1 to about 20 carbon atoms or alternatively R.sub.1 and R.sub.2 may together with the oxygen atoms to which they are joined form a heterocyclic ring containing two oxygen atoms.
