Patent ID: 8227541

Claim:
A composition containing components (I) and (II) wherein component (I) is a polypropylene homopolymer, random copolymer, alternating or segmented copolymer, block copolymer or a blend of polypropylene with another synthetic polymer; and component (II) is an additive mixture containing (A) at least one compound selected from the group consisting of formulae (I-1), (I-2) and (I-3) (B) a compound of formula (II-1) (C) at least one lubricant selected from the group consisting of Fischer-Tropsch wax, high-pressure polyethylene wax, Ziegler-Natta polyethylene wax, metallocene polyethylene wax, Ziegler-Natta polypropylene wax, stearamide, erucamide and oleamide, wherein the Fischer-Tropsch wax, high-pressure polyethylene wax, Ziegler-Natta polyethylene wax, metallocene polyethylene wax and Ziegler-Natta polypropylene wax have a molecular weight Mw of more than 800 g/mol and less than 20,000 g/mol and (D) at least one phenolic antioxidant selected from the group consisting of esters of β-(3,5-di-tert-butyl-4-hydroxyphenyl)propionic acid, β-(5-tert-butyl-4-hydroxyphenyl)propionic acid and β-(3,5-dicyclohexyl-4-hydroxyphenyl)propionic acid.
