Influence of Prepolymerization of MgCl2-supported TiCl4 Catalyst on Propene Polymerization and Properties of Resultant Polypropene Powder
Gažo, Peter ; Pospíšil, Ladislav (oponent) ; Kratochvíla, Jan (vedoucí práce)
The influence of pre–polymerization on the selected commercial MgCl2–supported TiCl4 catalyst (Ziegler–Natta) was studied. The work was focused on the evaluation of optimal conditions of pre–polymerization, which allow efficient modification of the selected catalyst and achievement of more stable process of the polymerization combined with better properties of produced polypropene. The influence of the temperature, concentration of triethylaluminum co–catalyst, external donor and amount of polyolefin synthetized during pre–polymerization (degree of pre–polymerization) on subsequent behavior of pre–polymerized catalyst in the gas-phase propene polymerization was evaluated.
