ABSTRACT:
The present invention provides a process for preparing microporous hollow fibers by solvent stretching a non-porous hollow precursor fiber having a controlled degree of molecular orientation as measured by birefringence. Control of the precursor fiber orientation, yields a microporous hollow fiber having an improved balance of mechanical strength and permeability.
