POLYMERS WITH IMPROVED ESCR FOR BLOW MOLDING APPLICATIONS |
摘要 |
Disclosed herein are ethylene-based polymers generally characterized by a density greater than 0.954 g/cm3, high load melt index ranging from 10 to 45 g/10 min, a ratio of high load melt index to melt index ranging from 175 to 600, a rheological slope parameter ranging from 0.15 to 0.30, and an ESCR in 10% igepal exceeding 800 hours. These polymers have the beneficial processability and die swell features of chromium-based resins, but with improved stiffness and stress crack resistance, and can be used in blow molding and other end-use applications. |
