Abstract:
The present invention relates to a hybrid supported metallocene catalyst and a polyolefin preparation method using the same. Using the hybrid supported metallocene catalyst can not only significantly reduce the amount of wax produced when polymerizing olefin monomers, but can also enhance the stress cracking resistance of the polyolefin that is prepared.
