Gas separation membrane |
| abstract |
This gas separation membrane contains a polyimide which has a repeating unit represented by formula (1). This gas separation membrane has excellent gas separation performance in a separation temperature range of from 35°C to 70°C (inclusive), and exhibits particularly excellent separation performance for CO 2 and CH 4 . Formula (1) (In formula (1), R 1 represents a divalent organic group represented by formula (2).) Formula (2) (In formula (2), R 2 represents a hydrogen atom, an alkyl group or a fluoroalkyl group; and a represents an integer of 1-2.) |
