Abstract: This invention relates to a molded article comprising an in-reactor polymer blend comprising: (a) a first propylene polymer comprising 90 to 100 wt % propylene and from 0 to less than 10 wt % comonomer, said first propylene component having a Tm of 135° C. or more; and (b) a second propylene polymer comprising from 30 to 90 wt % propylene and 70 to 10 wt % comonomer, said second propylene polymer having an Mw of 30,000 g/mol or more, and said second propylene-containing polymer having a crystallinity different by at least 5% from the first polymer, wherein the polymer blend has: (a) a Tm of at least 135° C., (b) a melt flow rate of at least 70 dg/min, (c) a tensile strength of at least 8 MPa, (d) an elongation at break of at least 200%, (e) a tensile strength at break of 10 MPa or more, and (f) a GME 60280 scratch resistance of less than 1.2 DL at a scratching load of 5 Newtons.
