ABSTRACT:
Compositions that are intimate blends of ultrahigh molecular weight polyethylene and high-density polyethylene (HDPE), and which are melt spinnable. The compositions include certain quasi-spherical particles. Also disclosed is a method of melt spinning from such compositions and the multi-filament fibers produced thereby. The fibers of the invention are useful in a variety of applications.
