Abstract
A gas separation membrane with excellent gas separation properties is disclosed. The gas separation membrane is substantially free from pinholes and consists essentially of a crosslinked polyolefin or a crosslinked polyarylene oxide. This gas separation membrane is produced by evaporating a solution containing a polyolefin or a polyarylene oxide having an active functional group which can form crosslinking site therebetween or which can react with a crosslinking agent to form a crosslinking site.
