Dual metallocene catalyst systems for decreasing melt index and increasing polymer production rates

Dual metallocene catalyst systems for decreasing melt index and increasing polymer production rates

The present invention provides dual catalyst systems and polymerization processes employing these dual catalyst systems. The disclosed polymerization processes can produce olefin polymers at higher production rates, and these olefin polymers may have a higher molecular weight and/or a lower melt ind...
