1-OLEFIN (CO)POLYMERIZATION CATALYST FOR PRODUCTION OF RESINS WITH A BROAD RANGE OF MOLECULAR WEIGHT DISTRIBUTION

摘要

2066625 9113914 PCTABS00007 A catalyst component and method of using such component in the polymerization of olefins to produce polyolefins of a targeted molecular weight distribution within a broad range of possible MWD's. The catalyst component is a supported Mg-Ti-V reaction product. MWD control is achieved by adding a controlled amount of halogenated hydrocarbon to the polymerization zone.
