摘要: A process for producing polyolefin materials is disclosed which comprises the steps of (a) preparing a molded article of an ultra-high-molecular-weight polyolefin having a viscosity-average molecular weight of more than 500,000; (b) stretching said article by more than thirty-fold; (c) contracting the thus stretched article to an extent ranging from 0.3 to 80% in the direction of stretch; and (d) re-stretching the thus contracted article. The resulting polyolefin materials are improved in mechanical strength and elasticity modulus.

摘要: 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.
