FIELD: chemistry of polymers. SUBSTANCE: ansa-bis-cyclopentadienyl derivatives of IV group transition metals where metal is in oxidation degree of +2 or +4 is prepared by contacting bis- cyclopentadienyl halogen, hydrocarbonyl (hydrocarbon radical), hydrocarbyloxide or amid complex of group IV metal with conjugated diene optionally in the presence of reducing agent. Metal complexes are useful as catalyst for polymerization of olefins, diolefins and/or acetylene unsaturated monomers. EFFECT: more efficient olefin polymerization method. 15 cl, 47 cl
