POLYETHYLENE PIPE RESINS AND PRODUCTION THEREOF

摘要

A polyethylene resin comprising a blend of from 35 to 49 wt% of a first polyethylene fraction of high molecular weight and 51 to 65 wt% of a second polyethylene fraction of low molecular weight, the first polyethylene fraction comprising a linear low density polyethylene having a density of up to 0.928 g/cm<3>, and an HLMI of less than 0.6 g/10min and the second polyethylene fraction comprising a high density polyethylene having a density of at least 0.969 g/cm<3> and an MI2 of greater than 100 g/10min, and the polyethylene resin, having a density of greater than 0.951 g/cm<3> and an HLMI of from 1 to 100 g/10min.
