Abstract: The present invention relates to polymer compositions comprising a propylene impact copolymer and a processing aid, as well as corrugated boards made from such compositions. The impact copolymer has a melt flow range of from 1.5 to 3.5 g/10 min and a dispersed phase content of from 5 to 30% by weight. The dispersed phase of the impact copolymer has an ethylene content of from 30- to 70% by weight of the dispersed phase. The matrix phase of the impact copolymer is a propylene homopolymer or a random copolymer comprising units derived from propylene and a second copolymer selected from either ethylene or 1-butene wherein the units derived from the second copolymer comprise from 0 to 5% by weight of the dispersed phase.

Abstract: Propylene impact copolymers (ICPs) are provided which comprise: (a) a matrix phase which comprises from 60 to 95 weight % of a polypropylene polymer containing from 0 to 6 mole % of units derived from one or more alpha-olefins other than propylene, and (b) a dispersed phase which comprises from 5 to 40 weight % of a copolymer derived from a first comonomer which can be either propylene or ethylene together with a second alpha-olefin comonomer. The ICP is further characterized by having a beta/alpha ratio less than or equal to 1.1. The ICPs of the present invention are particularly well suited for applications requiring clear, tough polymers such as thin walled injection molded articles for frozen food packaging applications.

Abstract: The present disclosure provides a molded article composed of a polymeric composition and processes for producing the same. The polymeric composition includes from about 60 wt % to about 99 wt % of a matrix of a propylene-based polymer. The propylene-based polymer has a refractive index (n1). The polymeric composition also includes from about 40 wt % to about 1 wt % of elongated elastomer particles dispersed in the propylene-based polymer. The elongated elastomer particles have a refractive index (n2). The propylene-based polymer and the elongated elastomer particles exhibit a refractive index mismatch whereby |n1?n2|>0.002. The molded article has a haze value less than about 20% and optionally a viscosity ratio (VR) greater than 0.28.
