ABSTRACT:
A process of forming shaped articles comprising forming a free draining gel from a solution of a crystallizable, high molecular weight polymer under conditions which cause crystallization of the polymer and subjecting the gel to a non-random deformation process so that the associated solvent is expressed. Some residual solvent may be present and can assist in subsequent fabrication processes but the solvent may also be completely removed for such processes. The resulting products have good physical properties, particularly in modulus after uniaxial or biaxial drawing.
