ABSTRACT:
A process for preparing a graft copolymers is provided comprising exposing a polymeric base material to a dose of ionizing radiation, and then contacting the irradiated base material with a microemulsion comprising at least one fluorostyrenic monomer, water and water-miscible solvent. The graft copolymer may be formed into a membrane, including ion exchange membranes.
