Abstract
Medium modulus molded polyethylene materials with improved impact strength are made. The polyethylene material is molded to pipes, bars, and sheets. The molded material comprises high molecular weight linear polyethylene and a substantially linear ethylene/.alpha.-olefin interpolymer. The material is more than about 0.23 mm thick, has a density in the range of about 0.923 to about 0.95 grams/cubic centimeter (g/cc) and has an excellent impact resistance.
