    Dicumylperoxide was used to crosslink ultra-high molecular weight polyethylene in the oriented state. Completely gelated fibre-networks with a tenacity up to 1.4 GPa were obtained. Storage at 195°C for 1 h left the tensile properties of the crosslinked filaments at room temperature practically unchanged, and vulcanization avoided fibre fibrillation upon failure. It was concluded that to combine high strength with high gel content, crosslinking should be peformed after the polyethylene chains have attained a high degree of orientation.
