ABSTRACT:
Dialkylaminomethylphenols such as 2,4,6-tris (dimethylaminomethyl) phenol are added, preferably along with another phenolic antioxidant prior to exposure to oxidative conditions, to a stereoregular polymer, a major portion of said polymer consisting of segmeric units derived from conjugated diolefin monomers, said polymer containing transition metal catalysts, to help prevent oxidative degradation of the polymer.
