ABSTRACT:
A catalyst composition for olefin polymerization and copolymerization which contains a transition metal complex with a bidentate or a tridentate ligand and a cocatalyst mixture containing dialkylaluminum halide and dialkylmagnesium.
The transition metal complexes with bidentate ligands L have the empirical formula LMX.sub.2, LMXY or L.sub.2 M where M is Ti, V, Zr or Hf; X is an alkoxy group, an aryloxy group, or a halogen atom; Y is a mono- or double-bonded ligand different from X.
The bidentate L ligands are described by general formulas
