ETHYLENE-BASED POLYMER, MANUFACTURING METHOD OF ETHYLENE-BASED POLYMER AND MANUFACTURING METHOD OF CATALYST FOR POLYMERIZATION, AND MOLDED ARTICLE OF HOLLOW PLASTICS CONTAINING ETHYLENE-BASED 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 alpha-olefin using a chromium catalyst.
