Low haze high strength polyethylene compositions

低浊度、高强度的聚乙烯组合物

Abstract

本发明涉及低密度基本上线性聚乙烯组合物,包括一些具有下列特性的聚乙烯组合物:(a)≤0.935g/cc的密度;(b)≤10%的浊度;(c)≥100g/mil的落镖冲击强度;(d)≥0.95的平均总长链支化指数;和(e)对于具有≥100,000的分子量的组合物的任何部分,≤0.85的分层长链支化指数(SLCB)。
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.
