An aqueous resin emulsion is disclosed. The emulsion is obtained by emulsion copolymerizing a monomer mixture comprising (a) an acrylic acid fluoroalkyl ester derivative, (b) an acrylic acid derivative, and (c) a polyfunctional monomer for internal cross-linking, in an aqueous medium. The emulsion shows excellent polymerization stability in emulsion copolymerization for the preparation thereof and excellent dispersion stability in an aqueous medium.

Aqueous resin emulsion

A process for preparing a selective permeable membrane having self-supporting property, which comprises coating on a supporting substrate a dope comprising a polyimide polymer consisting essentially of a repeating unit of the formula: ##STR1## wherein R is a divalent organic group, an inorganic salt and an organic solvent, as a dope solvent, which dissolves a mixture of the polymer and the inorganic salt to form a homogeneous system, to prepare a dope coated supporting substrate, heat treating the substrate at a temperature which does not cause the organic solvent in the dope to boil, and then coagulating the substrate.
