Kavesh Sheldon, Prevorsek Dusan Ciril: Process for producing high tenacity, high modulus crystalline thermoplastic article and novel product fibers.. Allied, November 10, 1982: EP0064167-A1 (47 worldwide citation)

Solutions of ultrahigh molecular weigh polymers such as polyethylene in a relatively non-volatile solvent are extruded through an aperture (25) at constant concentration through the aperture and cooled to form a first gel of indefinite length (33). The first gels are extracted (D) with a volatile so ...
