ABSTRACT:
Olefin polymer compositions are provided having enhanced stability against discoloration. The polymer compositions consist essentially of a normally solid olefin polymer such as polyethylene having incorporated therein, on a weight basis, 0.001 - 0.2 percent of 2,6-ditertiarybutyl-4-methylphenol* and 0.0005 - 0.4 percent of 2,6-ditertiarybutyl-4-ethylphenol**, with the quantity of 2,6-ditertiarybutyl-4-ethylphenol being present in a minimum amount of 50 weight % of the 2,6-ditertiarybutyl-4-methylphenol.
