    Abstract: The present invention is related to adhesive composition, having a polymer blend comprising a first propylene-based polymer, wherein the first propylene-based polymer is a homopolymer of propylene or a copolymer of propylene and ethylene or a C4 to C10 alpha-olefin, and a second propylene-based polymer, wherein the second propylene-based polymer is a homopolymer of propylene or a copolymer of propylene and ethylene or a C4 to C10 alpha-olefin; wherein the second propylene-based polymer is different than the first propylene-based polymer; wherein the polymer blend has a melt viscosity, measured at 190° C. and determined according to ASTM D-3236, of about 1,000 cP to about 5,000 cP; a propylene polymer; and wherein the adhesive composition is substantially free of a functionalized polyolefin, wherein the functionalized polyolefin is selected from at least one of a maleic anhydride-modified polypropylene and a maleic anhydride-modified polypropylene wax.

    Abstract: Disclosed is a thermoplastic polyolefin composition useful in automotive components comprising at least a polypropylene having a melting point temperature (Tm) of greater than 130° C. and a melt flow rate (230° C./2.16 kg) within the range from 10 g/10 min to 80 g/10 min; an amorphous ethylene-propylene copolymer comprising within the range from 40 wt % to 80 wt % ethylene derived units and having a melt flow rate (230° C./2.16 kg) within the range from 0.1 g/10 min to 20 g/10 min; and a propylene-based elastomer having within the range from 5 to 25 wt % ethylene derived units and having a Tm of less than 110° C. The composition only partially breaks or there is no break at −29° C. (ASTM D256) with Notched Izod Force of between 10 to 40 ft-lb/in2 at 22° C. (533 to 2,132 J/m2), and between 1.0 to 12 ft-lb/in2 at −29° C. (53 to 636 J/m2).
