    摘要: Plastics toughened plastics are metallocene catalyzed polyethylenes (mPE) and isotactic polypropylene (iPP). These plastic toughened plastics are useful in molded articles, most especially automotive interior trim parts. The mPE can be present in such toughened plastics from 5-40 weight percent, the iPP from 60-95 weight percent. The toughened plastics will have an excellent balance of tensile toughness, elongation and modulus at −10° C. Generally the tensile toughness will be 25-250% greater than the tensile toughness of a similarly proportioned blend of Ziegler-Natta catalyst produced polyethylene/iPP.
