ABSTRACT:
This invention involves polyethylene blends prepared by a particular method to achieve a unique solid state processability. More specifically, the polyethylene blends of this invention are high density polyethylenes (HDPE) blended in solution with a minor fraction of branched low density polyethylene, linear low density polyethylene or other polyethylene copolymers with a melting point significantly lower than that of HDPE. The HDPE blends described herein possess a unique large scale deformation characteristics below the melting pointing of the major HDPE component, such that the HDPE blends are suitable for solid state processing such as stamping or forging, etc.
