Abstract (en)

[origin: WO2016195868A1] 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 μιη), 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.
