Abstract

An oriented crystalline polymer includes a crystalline polymer which is oriented, preferably above its melting temperature, which is pliable in the absence of any plasticizing adjuvant, and which exhibits a tensile modulus E, measured in the drawing direction, of between 0.3 and 0.8 E.sub.0, E.sub.0 being the tensile modulus of the same polymer, unoriented.
