Abstract:
The present invention provides a non-metallocene transition metal compound that is easily produced, includes a tetrazol group having the high polymerization activity and high temperature stability in the polymerization of olefins, and a catalytic composition that includes the transition metal compound and a cocatalyst. In addition, the present invention provides a method for efficiently producing an olefin homopolymer or copolymer by using the catalytic composition.
