摘要：Provided are a supported metallocene catalyst which has excellent supportingefficiency due to an interaction between a cocatalyst supported on a carrier and ametallocene compound substituted with a functional group that can function as a Lewisbase, and a method of polymerizing an olefin using the supported metallocene catalyst.In the supported metallocene catalyst, the metallocene catalyst is strongly bound to thecarrier due to a Lewis acid-base interaction between the metallocene compound and thecocatalyst, and thus the metallocene catalyst is not separated from the carrier during thepolymerization of polyolefin in a slurry or gas phase method. Thus, fouling is preventedand the prepared polymer has a good particle shape and a high apparent density. Thus,the supported metallocene catalyst can be suitably used in a conventional slurry or gasphase polymerization process.
