ABSTRACT PRODUCING MODIFIED HIGH PERFORMANCE POLYOLEFIN FIBER Fibers prepared by spinning, drawing and drying dilute solutions of ultrahigh molecular weight polyethylene or polypropylene are modified by including in the dilute solution a polymeric additive. The poly- ethylene fibers so prepared have melting points above 140°C and exhibit improved adherence to matrices, resistance to fibrillation and other advantageous properties. Additives include lower molecular weight polyolefins, oxidized polyolefins, olefin copolymers, polyolefin graft copolymers and polyoxymethylenes.
