Abstract (en)
[origin: WO2016195870A1] 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 μιη), high surface area (SA≥ 400 m2/g), low pore volume (PV ≤ 2 mL/g), and a mean pore diameter range of 1≤ PD≤ 20 nm.
