| 摘要 |
A polymeric composition is provided comprising a random copolymer polypropylene, a hydrogenated block copolymer comprising at least two polymeric block containing predominately monoalkenyl aromatic hydrocarbon monomer units and at least one block containing a predominately hydrogenated, conjugated diene unit, and an elastic metallocene-based polyolefin. The polymer has improved impact strength and clarity, particularly at low temperatures.
