IMPROVED EASY PROCESSING LINEAR LOW DENSITY POLYETHYLENE

摘要

A polymer of ethylene and at least one alpha olefin having at least 5 carbon atoms obtainable by a continuous gas phase polymerization using supported catalyst of an activated molecularly discrete catalyst such as a metallocene in the substantial absence of an aluminum alkyl based scavenger, which polymer has a Melt Index (MI) as herein defined of from 0.1 to 15; a Compositional Distribution Breadth Index (CDBI) as defined herein of at least 70 %, a density of from 0.910 to 0.930 g/ml; a Haze value as herein defined of less than 20 %; a Melt Index ratio (MIR) as herein defined of from 35 to 80; an averaged Modulus (M) as herein defined of from 20 000 to 60 000 psi (pounds per square inch) and a relation bewteen M and the Dart Impact Strength in g/mil (DIS) complying with formula (I).
