Impact copolymers that comprise a continuous phase comprising a propylene-based polymer and a discontinuous rubber phase comprising a propylene/ethylene copolymer. The impact copolymers can have a fraction copolymer value (Fc) of at least 35, an ethylene content (Ec) of at least 38, a melt flow rate of at least 50 g/10 min and a notched Izod impact strength at 23 C of at least 615 J/m. |
