ABSTRACT:
Polyethylene compositions, which can be processed by injection molding, comprising 40% to 99% of a polyethylene having a limiting viscosity number of 1000 to 5000 ml/g and 60% to 1% of a polyethylene having a limiting viscosity number of 100 to 700 ml/g. The molecular weight distribution of each of the polyethylene components is less than 9. The limiting viscosity number of the compositions is at least 1500 ml/g. Shaped articles produced from these compositions have excellent wear resistance, high notched impact strength, and do not delaminate.
