POLYETHYLENE RESIN, CATALYST USED FOR PRODUCTION OF THE SAME, METHOD FOR PRODUCING THE SAME, HOLLOW PLASTIC MOLDED ARTICLE CONTAINING POLYETHYLENE RESIN, AND USE OF THE HOLLOW PLASTIC MOLDED ARTICLE

摘要

A polyethylene based resin exhibiting excellent moldability and durability and having an excellent balance between impact resistance and stiffness; and a hollow plastic molded article using the foregoing resin, which exhibits excellent moldability, durability and barrier properties and has an excellent balance between impact resistance and stiffness, are provided. The polyethylene based resin satisfies the following requirements (1) to (4): (1) a high-load melt flow rate (HLMFR) is from 1 to 100 g/10 min; (2) a density is from 0.940 to 0.960 g/cm 3 ; (3) a strain hardening parameter »max of elongational viscosity is from 1.05 to 1.50; and (4) a rupture time in a full notch tensile creep test and a density satisfy the following relational expression (A): log (rupture time) ‰¥ -355 × (density) + 337.6 (A).
