Abstract
This invention relates to high porosity (≥15%) and/or low pore diameter (PD<165 μm) propylene polymers and propylene polymerization processes using single site catalyst systems with supports having high surface area (SA≥400 m/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).
