Polyethylene polymer production catalyst and method for producing polyethylene polymer using the same |
| abstract |
PROBLEM TO BE SOLVED: To provide a catalyst for producing a polyethylene polymer, which can efficiently produce a polyethylene polymer having a low molecular weight and excellent wear resistance and having an ultra-high molecular weight. A polyethylene polymer comprising a metallocene catalyst comprising a hafnium-based transition metal compound (A) having a specific structure, an activation promoter (B) having a specific structure, and an organoaluminum compound (C). A production catalyst and a method for producing a polyethylene polymer using the catalyst. [Selection figure] None |
