Linear low density polyethylenes (LLDPEs) that have relatively high melt index ratios (MIR) and relatively high melt strength (MS) are described. This combination of melt properties is achieved by a substantially non-blended LLDPE. Catalysts used to produce these polyethylenes are generally a blend of...http://www.google.fr/patents/US20020143123?utm_source=gb-gplus-shareBrevet US20020143123 - Linear low density polyethylenes with high melt strength and high melt index ratio
