THE USE OF HYDROGEN SCAVENGING CATALYSTS TO CONTROL POLYMER MOLECULAR WEIGHT AND HYDROGEN LEVELS IN A POLYMERIZATION REACTOR

摘要

The present invention provides dual catalyst systems containing a metallocene catalyst and a hydrogen scavenging catalyst, and polymerization processes employing these dual catalyst systems. Due to a reduction in hydrogen levels in the polymerization processes, olefin polymers produced from these polymerization processes may have a higher molecular weight, a lower melt index, and higher levels of unsaturation.
