1. A process for preparing a polymer blend membrane, comprising:
(1) dissolving a polyether-based copolymer resin, a polyether oligomer containing a vinyl group, and an initiator in a solvent;
(2) subjecting the polyether oligomer containing a vinyl group to in-situ radical polymerization; and
(3) molding a product obtained in step (2) in the form of a membrane and removing the solvent therefrom.
