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 1):
A metallocene supported catalyst comprising one or more kinds of metallocene compounds, two or more kinds of cocatalyst compounds, and a carrier,\n wherein among the cocatalyst compounds, a first cocatalyst compound is a compound represented by the following Chemical Formula 1 and a second cocatalyst compound is diethyl zinc, and the diethyl zinc is included in the content of 0.1 to 3 mmol/g, based on the weight (g) of the carrier, and at least a part thereof is supported on the first cocatalyst compound:\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.
