Abstract

Two supported zirconocene catalysts were prepared: (I) SiO2/MAO/Me2Si(Ind)2ZrCl2 (0.1 wt. % Zr, 9.0 wt. % Al) and (II) MgCl2/Me2Si(Ind)2ZrCl2 (0.2 wt. % Zr, 1.6 wt. % Al). Ethylene was homopolymerized and copolymerized with 1-hexene (70-90°C, 6 bar, TIB A as cocatalyst) over (I) and (II). Catalyst (I) incorporated the comonomer as much as did the homogeneous catalyst of the same composition. MgCl2 used as support resulted in reduced copolymerization reactivity of the catalyst. Copolymer crystallinity and catalyst activity were studied in relation to the concentration of 1-hexene.
