Abstract

PURPOSE:To produce the membrane having high separating capacity and permeability, by dissolving the polymer of a norbornene derivative containing COOH group in a mono-(di) alkyl N-substitution product of an organic acid amide of carbon number of 1-2 and by forming the film from this solution in the specified condition.
