摘要: The present invention provides polyolefin compositions that are UV stable and suitable for articles may be exposed to sunlight. provides, in one aspect, a homopolymer or copolymer comprising, by weight of the polyolefin: (a) from 0.001 2 wt% hindered amine; (b) 1 ethoxylated (c) wt phenolic antioxidant; wherein amount antioxidant (PA), amine (EA) (HA) composition is satisfied equation: formula (I) Q ranges 0.15 250 when each component expressed as percentage. towards radiation such useful any number automotive components other are, example, injection molded.
