    Abstract: Embodiments are directed to polymer blends and molded articles including polymer blends. Embodiments of the polymer blend may include 1 to 40 wt. % of a crystalline block composite and from 60 wt. % to 99 wt. % of an ionomer formed from a partially neutralized precursor acid copolymer. The crystalline block composite may include an EP-iPP diblock polymer, an isotactic polypropylene homopolymer, and a copolymer of ethylene and propylene. The crystalline block composite may include greater than 50 wt. % of the isotactic polypropylene homopolymer. The precursor acid copolymer may include copolymerized units of ethylene and 5 wt. % to 30 wt. %, based on the total weight of the precursor acid copolymer, of copolymerized units of an α,β-ethylenically unsaturated carboxylic acid having 3 to 8 carbon atoms. About 25% to about 65% of the acid groups derived from the α,β-ethylenically unsaturated carboxylic acid of the precursor acid copolymer may be neutralized.

    Abstract: Embodiments relate to a high melt flow thermoplastic polyolefin composition and of a method of preparing a high melt flow thermoplastic polyolefin composition, in which the composition includes from 5 wt % to 45 wt % of a modifier including a blend of from 5 wt % to 40 wt % of a block composite and from 60 wt % to 95 wt % of a polyolefin copolymer, based on a total weight of the modifier, and from 30 wt % to 95 wt % of a polypropylene polymer base that has a melt flow rate of at least 40 g/10 min. The high melt flow thermoplastic polyolefin composition has a blended melt flow rate of at least 25 g/10 min and an MFR ratio is less than 2.0, the MFR ratio being a ratio of the melt flow rate of the polypropylene polymer base to the blended melt flow rate of the high melt flow thermoplastic polyolefin composition.
