Claim:
A method for producing a metallocene catalyst, the method comprising the steps of: reacting one or more of compounds that are represented by the following Formula 1 and Formula 2 with a compound that is represented by the following Formula 3 to bridge them with nitrogen; and reacting them with a compound that is represented by the following Formula 4 to coordinate them: wherein R 1 , R 2 , R 3 , R 4 , R 6 , R 7 , R 8 , R 9 , R 10 , R 11 , R 12 and R 13 may be the same or different from each other, and are each independently hydrogen; an alkyl group that is unsubstituted or substituted with a halo group and has 1 to 11 carbon atoms; an aryl group that is unsubstituted or substituted with a fluoroalkyl, nitro, sulfonate or halo group and has 6 to 20 carbon atoms; an arylalkyl group having 7 to 20 carbon atoms; an alkylaryl group having 7 to 20 carbon atoms; a nitro group; a sulfonate group; a siloxyl group; or —OSiZ 3 , Z is phenyl; a straight- or branched-chained hydrocarbon having 1 to 4 carbon atoms; a hydrocarbylene group; or —(BO) z Y, B is an alkylene group having 2 to 4 carbon atoms or an allylene group having 6 to 20 carbon atoms, Y is an alkyl group having 1 to 11 carbon atoms, a phenyl group, a biphenyl group, or a naphthyl group, and z is an integer in the range of 1 to 4, X is a halogen atom or a thallium atom, R 5 —NH 2 [Formula 3] wherein R 5 is an alkyl group having 1 to 11 carbon atoms; an aryl group that is unsubstituted or substituted with a fluoroalkyl, nitro, sulfonate or halo group and has 6 to 20 carbon atoms; an arylalkyl group having 7 to 20 carbon atoms; or an alkylaryl group having 7 to 20 carbon atoms, MA x r Q [Formula 4] wherein M is a Group 3 to 11 transition metal, A is Cl or Br, X is an integer in the range of 2 to 4, r is an integer in the range of 1 to 4, and Q is THF (tetrahydrofuran), Et 2 O (diethylether), or DME (Dimethyl Ether).
