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.
