    • Disclosed are a method for producing a polymer support using metallic ion complex compounds and a method for producing a pervaporation membrane using the polymer support. The method for producing a polymer support according to the present invention comprises the steps of: producing a casting solution including a polymer resin, an organic polar aprotic solvent, and metallic ion complex compounds; solidifying the polymer resin by casting the casting solution on a support to have a predetermined thickness and then by dipping the casting solution in a non-solvent; washing the solidified polymer resin and separating the solidified polymer resin from the support; and drying the separated polymer resin. Moreover, the method for producing a pervaporation membrane according to the present invention further comprises the steps of: producing a coating solution including siloxane compounds and an organic solvent; and coating the coating solution on the polymer support produced by the method and drying the coated coating solution.
