OLEFIN POLYMERIZATION CATALYST CONTAINING A TRANSITION METAL COMPLEX AND PROCESS FOR PRODUCING OLEFIN POLYMERS

摘要

A transition metal complex represented by the formula (1) wherein M<1> is a transition metal atom of the group 4 of the periodic table of elements, A is an atom of the group 16 of the periodic table of elements, and B is an atom of the group 14 of the periodic table of elements; Cp<1> is a group having a cyclopentadiene type anionic skeleton; and X<1>, X<2>, R<1>, R<2>, R<3>, R<4>, R<5> and R<6> are each independently a hydrogen atom, halogen atom, alkyl group with the number of carbon atoms of 1-20 optionally substituted with at least one halogen atom, aralkyl group with the number of carbon atoms of 7-20 optionally substituted with at least one halogen atom, aryl group with the number of carbon atoms of 6-20 optionally substituted with at least one halogen atom, substituted silyl group with the number of carbon atoms of 1-20 optionally substituted with at least one halogen atom, alkoxy group with the number of carbon atoms of 1-20 optionally substituted with at least one halogen atom, aralkyloxy group with the number of carbon atoms of 7-20 optionally substituted with at least one halogen atom or aryloxy group with the number of carbon atoms of 6-20 optionally substituted with at least one halogen atom, or di-substituted amino group with the number of carbon atoms of 2-20, provided that R<1>, R<2>, R<3>, R<4>, R<5> and R<6> may optionally combine with each other to form a ring; a process for producing the same; an olefin polymerization catalyst containing the transition metal complex; and a process for producing olefin polymers.
