ETHYLENE POLYMER, PROCESS FOR PRODUCING ETHYLENE POLYMER, PROCESS FOR PRODUCING POLYMERIZATION CATALYST, AND HOLLOW PLASTIC MOLDING COMPRISING ETHYLENE POLYMER AND USE THEREOF

摘要

An object of the invention is to provide an ethylene-based polymer excellent in moldability and durability, and also excellent in the balance of stiffness and durability, and to provide a molded product of hollow plastic using the ethylene-based polymer. The ethylene-based polymer according to the invention is an ethylene-based polymer having specific characteristics and manufactured by a homopolymerization of ethylene or a copolymerization of ethylene and ±-olefin using a chromium catalyst.
