POLYETHYLENE HAVING IMPROVED BRANCHING DEGREE DISTRIBUTION |
摘要 |
An object of the present invention is to provide polyethylene having excellent moldability and impact resistance and excellent balance between rigidity and durability, produced using a novel organoaluminum compound-supported chromium catalyst, a method for producing polyethylene, and a hollow plastic molding containing the polyethylene. The polyethylene of the invention is polymerized using a chromium catalyst, and has a weight average molecular weight (Mw) of 30,000 or more at the maximum value in a branching degree distribution curve that shows a molecular weight dependency of short chain branches having 4 or more carbon atoms. |
