Title:
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
Document Type and Number:
WIPO Patent Application WO/2010/150410
Kind Code:
A1
Abstract:
Disclosed is a polyethylene resin exhibiting excellent moldability and durability, while having an excellent balance between impact resistance and rigidity. Also disclosed is a hollow plastic molded article which uses the resin and exhibits excellent moldability, durability and barrier properties, while having an excellent balance between impact resistance and rigidity. The polyethylene resin satisfies the following conditions (1)-(4).
(1) The high-load melt flow rate (HLMFR) is within the range of 1-100 g/10 min.
(2) The density is within the range of 0.940-0.960 g/cm3.
(3) The strain hardening parameter of elongation viscosity (λmax) is within the range of 1.05-1.50.
(4) The rupture time in an all-around notch type tensile creep test and the density satisfy the following formula (A).
log (rupture time) ≥ -335 × (density) + 337.6 (A)
