Linear low density polyethylenes with high melt strength and high melt index ratio |
摘要 |
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.
