ABSTRACT:
The present invention provides a split polyethylene stretched material having a tensile strength of at least 0.7 GPa when twisted in the range of 50-500 times/m, which material is produced by subjecting a polyethylene having an intrinsic viscosity of 5-50 dl/g as measured at 135.degree. C. in decalin, i.e. an ultra-high-molecular-weight polyethylene to stretching and then subjecting the stretched polyethylene to splitting, as well as a process for producing said material. The split polyethylene stretched material according to the present invention has a large surface area and accordingly can be easily laminated to other materials, and has a high strength and flexibility.
