PURPOSE: A manufacturing method of a supported metallocene is provided to have high activity by using a little activating material and to prevent fouling or clogging of transfer channels in the supported metallocene catalyst. CONSTITUTION: A manufacturing method of a supported metallocene comprises a step of adding a solvent into a support and dropping alkyl aluminoxane solution; a step of adding a metallocene catalyst compound and activating agent into the solution and stirring the mixture for reactions; and a step of filtering and washing the product, and removing solvent from the product. The alkyl aluminoxane solution comprises 5-30 wt% of alkyl aluminoxane, 5-15 wt% of trialkylaluminum, and 50-85 wt% of toluene. |
