Copolymerization of Ethylene and ۱-Hexene Using MgCl۲-Adduct-Supported Metallocene Catalyst

Recently, the use of metallocene catalysts for producing ethylene based copolymers and long-chainalpha-olefins has garnered significant attention due to their high acceptance of comonomers.Additionally, supporting these types of catalysts for use in slurry and gas-phase polymerizationsystems has been proposed. In this project, ۲ types of metallocene catalysts Cp۲TiCl۲ and Cp۲ZrCl۲were supported on a magnesium chloride support at concentrations of ۲, ۱۰, and ۲۰ μmol. Thesupported catalysts were then used in the polymerization of ethylene with the assistanceof triethylaluminium (TEA). The activity of the catalysts and the properties of the resulting polymerswere subsequently investigated and compared.
