摘要：
A transition metal compound which is a multiple crosslinking type transition metal complex represented by the general formula (I) ##STR1## wherein M is a metallic element in the groups 3 to 10 or a lanthanoide series of the periodic table; E.sup.1 and E.sup.2 are each a .sigma.-bonding or a .pi.-bonding ligand; X is a .sigma.-bonding ligand; L is a Lewis base; A.sup.1, A.sup.2 . . . A.sup.n and D arc each a crosslinking group; n is 2 to 4; p is 1 to 4; q is 1 to 5; r is 0 to 3; and s is 0 to 4; and catalysts for olefin polymerization containing the transition metal compound or complexes thereof and a process for preparing an olefin polymer employing the catalyst.
