Supported dichlorobis(3-hydroxi-2-methyl-4-pyrone)Ti(IV) catalysts: Evaluation on ethylene polymerization

Titanium complex bearing 3-hydroxi-2-methyl-4-pyrone as ligand was grafted on different inorganic carriers, namely SiO2, MAO-modified silica, MCM-41, Al2O3, ZrO2 and MgO. The resulting supported catalysts were shown to be active in ethylene polymerization using methylaluminoxane (MAO) as cocatalyst, most of them being even more active that the homogeneous complex.
