Abstract
This invention relates to heterophasic copolymers of propylene and an alpha olefin comonomer having a high fill phase content (≥15%), and heterophasic polymerization processes using a single site catalyst system with a support having high average particle size (PS≥30 μm), high surface area (SA≥400 m/g), low pore volume (PV≤2 mL/g), and a mean pore diameter range of 1≤PD≤20 nm.
