摘要： A high modulus polymer material is produced by subjecting a crystallisable polymer to a thermal treatment under conditions such that the possibility that a given molecular chain is incorporated in more than one crystal lamella is substantially reduced and then attenuating the polymer at an imposed rate and temperature whereby substantially complete alignment of its molecules may be obtained.

摘要： A process for the production of a high modulus filament of polyethylene which comprises heating high density polyethylene to a temperature above its melting point, extruding the polymer to form a filament, subjecting the filament immediately after extrusion to a tension under such conditions that the filament is shaped without substantial orientation of its molecules, cooling the filament at a rate of cooling in excess of 15.degree. C. per minute, and drawing the filament to a high draw ratio.
