Stabilized compositions of alpha-olefinic polymers.

摘要

1. Compositions which are stabilised against oxidative degradation and are based on alpha-olefine polymers containing a phenolic primary antioxidant and belonging to the group of the alkylated mono-, bis- and thiobisphenols, characterised in that they additionally comprise a secondary antioxidant chosen from among phenolic polyesters derived from a polyfunctional aliphatic or aromatic carboxylic acid and an alkylated polyphenol.
