A casting solution of two nylons in formic acid, e.g., high molecular weight extrusion grade Nylon 66 homopolymer [ eta ] about 2 or higher, and nylon multipolymer 66, 610, 6 as a strengthening polymer and gelation promoter, when cast by either the dry or wet phase inversion processes, results in highly unexpected membranes of superior strength, flexibility, and uniformity, suitable for use in microfiltration and ultrafiltration.
