Summary: | A stabilized polypropylene composition, free or essentially free of any phenolic antioxidant containing: a) 100 parts by weight of a propylene polymer, b) from 0.005 to 0.1 part by weight of an amine oxide having the structural formula wherein R' and R'' are groups containing from 1 to 36 carbon atoms, or of a N,N-dialkylhydroxylamine of formula R1R2NOH (II) wherein R1 and R2 are independent groups of 1 to 36 carbon atoms, c) from 0.1 to 0.5 part by weight of a clarifying agent, and optionally d) from 0.01 to 0.1 part by weight of a sterically hindered amine. Manufacture of shaped object by using said composition and manufactured objects so obtained. |
