POLYOLEFINS STABILIZED AGAINST OXIDATIVE DEGRADATION WITH MIXTURES OF ARALKYL-SUBSTITUTED DIARYLAMINES AND STERICALLY HINDERED PHOSPHITES

摘要

A polyolefin is stabilized against oxidative degradation by the presence therein of a stabilizing amount of an antioxidant composition which comprises: a) at least one aralkyl-substituted diarylamine; and, b) at least one sterically hindered phosphite. g
