PROBLEM TO BE SOLVED: To provide a method for producing a polymer film that has high uniformity in thickness direction and that is useful as a separation membrane of carbon dioxide, and to provide a gas separation membrane. SOLUTION: In the method for producing the polymer film, under existence of amine compound having a group expressed by general formula (1):-X-[-CH(-OH)-]n-CH<SB>2</SB>NH<SB>2</SB>, there is immobilized the amine compound in a polymer that is formed by polymerization reaction by irradiating polyfunctional polymerizable monomer with at least one of radioactive rays, electron beams or ion beams. In the formula, X denotes -CO-NH- or -NH-CO-, Y denotes 2-valence organic residue with a carbon number of 1-3, and n denotes an integer of 0 or 1. COPYRIGHT: (C)2011,JPO&INPIT |
