Linear Low Density Polyethylene Prepared in Gas Phase with Bisupported SiO2-MgCl2 Ziegler-Natta Catalysts

Summary

Bisupported silica-MgCl2-TiCl4 catalysts suited for gas phase polymerization are used at 15 bars, 85–95°C for the synthesis of polyethylenes ranging from high density to linear low density. The main parameters of the reaction (temperature, pressure, monomer ratio) are studied in connection with the pecularities of the gas phase polymerization. The effect of the addition of a Lewis base to the solid catalyst on copolymerization reactivity and on the copolymer structure are studied.
