Automotive articles prepared from filled tpo compositions, and methods of making the same

Polyolefin composition, molded article, method for preparing a composition. Compositions comprising (i) a crystalline isotactic propylene homopolymer, (ii) an ethylene / α-olefin elastomeric impact modifier, and (iii) a reinforcing filler category, such as talc. The crystalline isotactic propylene homopolymer has a flexural modulus greater than about 1930 mpa and a thermal distortion temperature (hdt) greater than about 100 ° C; The ethylene / α-olefin interpolymer has a tg of less than about -30 ° C, and a tan delta measured at 0.1 radians / s at 190 ° C or less than about 2; And the filler has a hdt boosting efficiency of at least about 2. The composition has an hdt greater than about 100 ° C and a flexural modulus greater than about 1930 mpa.
