    摘要: Impact polymer compositions and peroxide-treated derivatives thereof demonstrate a good balance of low temperature properties and resistance to stress whitening when the homopolymer phase is at least predominantly homopolymeric propylene polymer and the rubber phase comprises, in descending order of proportion, ethylene, units of an a-olefin of at least 4 carbon atoms and propylene units.

    摘要: Polypropylene impact copolymer compositions demonstrate not only good low temperature properties, including impact strength, but also resistance to stress whitening when the numerical ratio of the intrinsic viscosity of a copolymer phase to the intrinsic viscosity of a homopolymer phase is from 0.7/1 to 1.3/1. The impact copolymer compositions are useful in the production of molded and extruded articles, shaped containers, and films having good clarity.
