    • The new metallocene catalysts according to the present invention are prepared by reacting a metallocene compound with a compound having at least two functional groups. The metallocene compound is a transition metal compound which a transition metal is coordinated with a main ligand such as cycloalkanedienyl group and an ancillary ligand. The functional groups of the compound having at least two functional groups are selected from the group consisting of a hydroxy group, a thiol group, a primary amine group, a secondary amine group, etc. The metallocene catalysts according to the present invention have a structure which an ancillary ligand of a metallocene compound is bonded with functional groups. A structure of the metallocene catalysts can be varied according to the metallocene compounds, the compound having at least two functional groups, and the molar ratio of each reactant. The metallocene catalyst is employed with a co-catalyst for styrene and olefin polymerization. The co-catalyst is an organometallic compound and a mixture of non-coordinated Lewis acid and alkylaluminium. The organometallic compound is usually alkylaluminoxane and organoaluminium compound. The syndiotactic polystyrenes and the polyolefins having good physical properties are prepared by using the metallocene catalyst according to the present invention. A monomer for polymerization includes styrene, derivatives of styrene, and a compound having ethylenically unsaturated double bonds. Those compounds are homopolymerized and copolymerized to give polystyrene and polyolefin.
