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 end extruded articles, shaped container, and films having good clarity.
