    摘要: Multi-component catalyst systems for polymerization and copolymerization of olefins consist of at least one transition metal complex containing a multidentate ligand and a three-component cocatalyst. The transition metal complexes with bidentate ligands L have empirical formulasLMX.sub.2, LMXY or L.sub.2 Mwhere M is Ti, V, Zr or Hf atom; X is an alkoxy group, an aryloxy group, or a halogen atom; Y is a mono- or double-bonded ligand different from X. Complexes with tridentate ligands L' have empirical formulas L'MX where M is Ti, V, Zr or Hf; X is an alkoxy group, an aryloxy group, or a halogen atom. Examples of L and L' are alkyldioxy, alkyldiamino, alkyldicarboxy, biaryldioxy, or alkylaminodioxy ligands; particular examples of X are the isopropoxy group or Cl; a particular example of Y is an oxygen atom. The preferred substitution types in the multidentate ligands L and L' are such which afford their unimpeded coordination to the metal atom M in tri-, tetra- or pentacoordinated complexes. The transition metal complexes can be used in pure state or supported on an inert carrier.
