Abstract

See full text

This invention relates to catalyst supports having high surface area (SA≥400 m2/g), low pore volume (PV≤2 mL/g), a specific mean pore diameter range (PD=1-20 nm), and high average particle size (PS≥30 μm), supported catalysts, and supportation processes; and further relates to: high porosity (≥15%) and/or low pore diameter (PD<165 μm) propylene polymers; bimodal polymers and/or heterophasic copolymers based on the high porosity and/or low pore diameter propylene polymers; propylene polymerization processes using the supported catalysts and/or to prepare the high porosity and/or low pore diameter propylene polymers, bimodal polymers and/or heterophasic copolymers.
