This invention relates to hetero-phase polyolefin compositions comprising: a) 30 to 99.7 wt % of a polypropylene-based TPO comprising at least 50 wt % propylene and at least 10 wt % ethylene, and b) 0.1 to 20 wt % of one or more non-functionalized plasticizer, and c) 0.2 to 50 wt % of one or more filler; based upon the weight of the composition, and having: i) an MFR of 5 dg/min or more, and ii) a flexural modulus of 500 MPa or more, and iii) a notched Charpy impact strength at &#x2212;30&#xb0; C. of 1 kJ/mor more or a notched Izod impact strength at &#x2212;18&#xb0; C. of 50 J/m or more. These compositions are especially useful in applications such as automotive parts that demand both high stiffness and high impact toughness, as well as good processibility during fabrication.

Plasticized hetero-phase polyolefin blends

Provided is a polymer composition comprising a thermoplastic, an ethylene alpha-olefin plastomer, a fibrous inosilicate and a slip agent. The polymer composition exhibits superior scratch and mar resistance as indicated by a Ford Five Finger scratch resistance on Ford Fawn 2ZK grain of at least 15 N. Also provided are shaped articles made from the polymer compositions. Also provided are methods for making scratch and mar resistant polymer compositions. Finally, articles made from the polymer compositions are also provided, particularly automotive exterior, interior and fascia parts, requiring scratch and mar resistance.
