Polypropylene or peroxide-free polyolefins are stabilized against oxidative degradation by the presence therein of a stabilizing amount of an antioxidant composition which comprises:
a) at least one diarylamine selected from the group consisting of alkyl-substituted diarylamine and aralkyl-substituted diarylyamine and;
b) at least one sterically hindered phenol.
在聚丙烯或不含过氧化物的聚烯烃中加入一定量的稳定抗氧化剂组合物,可防止其氧化降解:
a) 至少一种二芳胺,选自由烷基取代的二芳胺和芳烷基取代的二芳胺组成的组;
b) 至少一种立体受阻酚。
