Abstract
A method of producing high modulus and strength polymer materials includes compressive rolling a semicrystalline polymer material in at least two different axial directions of the material; and axially orienting at least a portion of the compressive rolled material to a draw ratio less than the ultimate elongation or the elongation % at break of the material.
