Abstract:
The present invention provides a metallocene supported catalyst that can prepare a polyolefin having excellent transparency even when processed into a film, as well as excellent processibility and mechanical properties, with high catalytic activity, and a method for preparing a polyolefin using the same.

Claim (Index 6):
A method for preparing a metallocene supported catalyst comprising the steps of supporting two or more kinds of cocatalyst compounds on a carrier, and then supporting one or more kinds of metallocene compounds,\n wherein among the cocatalyst compounds, the first cocatalyst compound is a compound represented by the following Chemical Formula 1 and the second cocatalyst compound is diethyl zinc, and the diethyl zinc is supported in the content of 0.1 to 3 mmol/g based on the weight (g) of the carrier, after the first cocatalyst compound is supported:\n \u2014[Al(R a )\u2014O] n \u2014\u2003\u2003[Chemical Formula 1] \n wherein, in Chemical Formula 1, each R a  is identical to or different from each other, and are independently a halogen, a C1-20 hydrocarbon, or a C1-20 hydrocarbon substituted with a halogen; and n is an integer of 2 or more.
