    摘要: A polymeric material suitable for fabrication into an article and particularly a polymeric material suitable for fabrication into an article suitable for receiving paint is provided. The polymeric material may be a blend of impact copolymer and plastomer. The impact copolymer includes between 95 and 78 wt % homopolypropylene and between 5 and 22 wt % of ethylene-propylene rubber, wherein ethylene propylene rubber may have less than about 50 wt % ethylene. The plastomer may be an ethylene/hexene plastomer. The ethylene/hexene plastomer may have a density in the range from 0.88 to 0.915 g/cc and a melt index (dg/min) from 0.8 to 10. The impact copolymer may be present in the blend in a range of 95 to 70 wt % and the ethylene/hexene plastomer may be present in the blend in a range from 5 to 30 wt %. The propylene, ethylene and hexene components may be present in the blend in respective ranges of 73.2 to 84.2 wt %, 14.3 to 23.1 wt % and 1.5 to 3.7 wt %.

    摘要: Plastic toughened plastics include a polymer composition having a polypropylene component and a second polymer component. The polypropylene component is present in an amount from about 50 to about 95 weight percent based on the total weight of the blend. The second polymer component is present in an amount from about 5 to about 50 weight percent based on the total weight of the blend, is a BOCD or BCD blend of at least two ssPE components, and has an overall density greater than about 0.90 g/cm3. Optionally, the plastic toughened plastics include one or more third polymer component selected from propylene-olefin elastomers and ethylene-propylene rubbers, which are present in an amount from about 1 to about 50 weight percent, based on the total weight of the blend.
