Abstract (en)
[origin: WO2016195867A1] This invention relates to high porosity (>15%) and/or low pore diameter (PD < 165 μιη) propylene polymers and propylene polymerization processes using single site catalyst systems with 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).
