Linear low density polyethylenes with high melt strength and high melt index ratio

Linear low density polyethylenes (LLDPES) that have relatively high melt index ratios (MIR) and relatively high melt strength (MS). This combination of melt properties is achieved by a substantially non blended LLDPE. Catalysts used to produce these polyethylenes are generally a blend of bridged bis...

Summary:Linear low density polyethylenes (LLDPES) that have relatively high melt index ratios (MIR) and relatively high melt strength (MS). This combination of melt properties is achieved by a substantially non blended LLDPE. Catalysts used to produce these polyethylenes are generally a blend of bridged bisindenyl zirconocene dichlorides, where one zirconocene contains saturated indenyls and the other unsaturated indenyls.
