POLYMERS WITH IMPROVED TOUGHNESS AND ESCR FOR LARGE-PART BLOW MOLDING APPLICATIONS |
摘要 |
<p>Disclosed herein are ethylene-based polymers having a density greater than 0.945 g/cm3, a high load melt index less than 25 g/10 min, a peak molecular weight ranging from 52,000 to 132,000 g/mol, and an environmental stress crack resistance of at least 250 hours. These polymers have the processability of chromium-based resins, but with improved impact strength and stress crack resistance, and can be used in large-part blow molding applications.</p> |
