Abstract: A polypropylene impact copolymer is disclosed. The propylene impact copolymer composition comprises from 60 to 90 percent by weight of the impact copolymer composition of a matrix phase, which can be a homopolymer polypropylene or random polypropylene copolymer having from 0.1 to 7 mol percent of units derived from ethylene or C4-C10 alpha olefins. The propylene impact copolymer composition also comprises from 10 to 40 percent by weight of the impact copolymer composition of a dispersed phase, which comprises a propylene/alpha-olefin copolymer having from 6 to 40 mol percent of units derived from ethylene or C4-C10 alpha olefins, wherein the dispersed phase has a comonomer content which is greater than the comonomer content in the matrix phase. The propylene impact copolymer composition is further characterized by having the ratio of the dispersed phase intrinsic viscosity (IV) to the matrix phase IV being 0.95 or less.

Abstract: Disclosed is a multimodal propylene impact copolymer composition with improved stiffness while maintaining good impact strength. The continuous phase has a broad PI and provides the multimodal propylene impact copolymer composition with excellent processability. Thermoformed articles made from the multimodal propylene impact copolymer exhibit improved rigidity and good impact strength.
