Catalyst for producing ultra high molecular weight polyethylene polymer and method for producing ultra high molecular weight polyethylene polymer using the same

摘要

PROBLEM TO BE SOLVED: To provide a catalyst for producing an ultrahigh-molecular weight polyethylene polymer that makes it possible to efficiently produce ultrahigh-molecular weight polyethylene polymer that has an inherent viscosity of 40 dL/g or more or a viscosity conversion molecular weight (Mv) of 12000,000 or more.SOLUTION: A catalyst for producing an ultrahigh-molecular weight polyethylene polymer comprises a metallocene catalyst comprising a transition metal compound (A) having a specific structure, an organic modified clay (B) modified with aliphatic salt having a specific structure, and an organic aluminum compound (C). There is also provided a method of producing an ultrahigh-molecular weight polyethylene polymer using the same.SELECTED DRAWING: None
