The present invention relates to a process for produc- ing a stretched molding which comprises stretching a straight chain random copolymer having: a repeating unit (A) represented by the formula: ?CH2-CH2? and a repeating unit (B) represented by the formula: Image the proportion of said repeating unit (B) being 0.01 to 10 mol%; and an intrinsic viscosity [?] as measured at 135°C in decalin of at least 5 d?/g. A stretched molding obtained by the present invention has mechanical properties equivalent or superior to those of the conventional super high molecular weight polyethylene stretched molding and is excellent in adhesive properties, dyeability, printability and so on, and thus is greatly useful as an industrial material required to have high strength and further good adhesive properties and printability.
