Metal compounds, and use of the metal compound in olefin polymerization

Formula I [Formula 1] In expressed, metal compound M represents Ni or Pd of oxidation state + II can be used in the polymerization or copolymerization of olefins. Catalyst having a carrier used for the polymerization or copolymerization of olefins is obtained by subjecting one or more of the non-ionic compound to the carrier.
