Abstract

A polymer composite, a method of making a polymer composite and a polymer composite membrane. The polymer composite comprises a uniform dispersion of hydrophobic polymeric particles in a continuous phase of a hydrophilic polymer. The new method of forming a polymer composite includes the formation of a concentrated emulsion of a hydrophilic monomer and a hydrophobic monomer and heating the concentrated emulsion at a predetermined temperature. The polymer composites of this invention may be useful as permselective membranes.
