Abstract: A composition comprising: (i) at least one low molecular weight polyolefin; (ii) at least one block copolymer obtainable by selectively hydrogenating a block copolymer having terminal polymeric blocks of a vinyl aromatic monomer and a mid-block prepared originally with an olefin and subsequently hydrogenated; (iii) at least one polypropylene; and (iv) at least one plastomer, wherein the plastomer is an ethylene based polymer having a density of 0.86 g/cc to about 0.910 g/cc or a propylene based polymer having a heat of fusion (Hf) of 70 J/g or less.

Abstract: Branched crystalline polypropylene compositions and methods for the preparation of branched crystalline polypropylene compositions are provided. For example, described herein is a process of preparing a branched crystalline polypropylene composition that includes combining two or more different metallocene catalyst compounds with a polymerization medium that includes propylene, for a time sufficient to provide branched crystalline polypropylene that has from 0.0 wt % to 2.0 wt % ethylene and a heat of fusion of 70 J/g or more.
