PROBLEM TO BE SOLVED: To provide a highly selective and highly active metallocene catalyst which is excellent in stereoregularity, has a high melting temperature and can produce polyolefin, polystyrene and the like having a good molecular weight. SOLUTION: A transition metal of Group 3 (III) to Group 10 (X) of the periodic table, in which a cycloalkanegen group as a main ligand and one or more auxiliary ligands are bonded, A metallocene catalyst is synthesized from a compound having two or more functional groups. |
