ABSTRACT:
A polyolefin composition is disclosed comprising polyolefin with a synergistic antioxidant composition of a phenolic oxidation inhibitor and synergist capable of reacting with the phenoxyl radicals to form a phenolic group and regenerate the phenolic oxidation inhibitor. In a preferred embodiment of the invention, the synergist also acts as a metal-complexing agent capable of complexing with trace transition-metal-ions contaminants in the polyolefin.
