Polymeric composition, its use for the manufacture of object and object so obtained

摘要

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 <CHEM> wherein R' and R" are groups containing from 1 to 36 carbon atoms, or of a N,N-dialkylhydroxylamine of formula R<1> R<2> NOH wherein R<1> and R<2> 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.
