Zusammenfassung:PROBLEM TO BE SOLVED: To provide a polymer including a polyolefin such as a polypropylene, etc., with enhanced antioxidant characteristics, processability and heat stability by adding a specific compound to the polymer. SOLUTION: A polymer is mixed with preferably 0.01-5 wt.%, more preferably 0.01-0.5 wt.%, especially preferably 0.05-0.25 wt.% based on the polymer of a compound of formula I [R is H, a lower alkyl or phenyl; Ar is a monocyclic or condensed polycyclic aromatic group containing
