LOW HAZE HIGH STRENGTH POLYETHYLENE COMPOSITIONS

摘要

A low density substantially linear polyethylene composition is described, including some that have: (a) a density of 0.935 g/cc or less; (b) a Haze of 10% or less, (c) a Dart Impact of 100 grams/mil or more, (d) an average overall long chain branching index of 0.95 or more; and (e) a slice long chain branching (SLCB) index of 0.85 or less for any portion of the composition having a molecular weight of 100,000 or above.
