Abstract

Processes for forming polymer fibers, comprising: (a) providing a colloidal dispersion of at least one essentially water-insoluble polymer in an aqueous medium; and (b) electrospinning the colloidal dispersion; polymer fibers prepared by such processes; and colloidal dispersions comprising: at least one essentially water-insoluble polymer in an aqueous medium; and at least 10% by weight of a water-soluble polymer having a solubility in water of at least 0.1% by weight.
