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.
