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