Abstract: Very high molecular weight polyethylene compositions obtained from the blending of high density polyethylene and ultra high molecular weight polyethylene and a method for preparing the same are disclosed. The blending is effected by forming a first blend by incorporating ultra high molecular weight polyethylene into high density polyethylene material in an amount wherein the high density polyethylene remains as the matrix for the ultra high molecular weight polyethylene particles, forming a second blend by incorporating ultra high molecular weight polyethylene into high density polyethylene in an amount which is sufficiently large so that the ultra high molecular weight polyethylene becomes the matrix of the compound, and by blending the first and second blends. The compositions exhibit thermoplastic properties similar to those of high density so that they can be melt processed to obtain end use products that have improved abrasion resistance.
