Abstract

1. Introduction : Gas transport through dense polymeric membranes is predominantly determined by the chain packing density as well as the chain flexibility. Thus, improved permeation properties can be obtained by controlling these two factors. In this work, the introduction of bulky substituents was attempted to improve permeation properties. Polysulfone, widely used material for gas separation membrane, was the starting material of this modification. Gas transport properties of resulting modified polysulfones were examined, and the improved properties were explained by probing the change of physical properties.
