%X Polymeric membranes are widely used for gas separation purposes but their performance is restricted by the upper bound trade-off discovered by Robeson in 1991. The polymeric membrane can be glassy, rubbery or a blend of these two polymers. This review paper discusses the properties of glassy polymer membranes and their performance in gas separation. The area of improvement for glassy membrane with development of mixed matrix membrane is also highlighted. © 2014 Trans Tech Publications, Switzerland. %K Catalyst selectivity; Economic and social effects; Glass; Mechanical permeability; Membranes; Polymeric membranes; Polymers; Separation, Gas separations; Glassy polymers; Mixed matrix membranes; Review papers; Trade off; Upper Bound, Gas permeable membranes %O cited By 16; Conference of 3rd International Conference on Process Engineering and Advanced Materials, ICPEAM 2014 ; Conference Date: 3 June 2014 Through 5 June 2014; Conference Code:114811 %L scholars4749 %J Applied Mechanics and Materials %D 2014 %R 10.4028/www.scientific.net/AMM.625.701 %T A review on glassy polymeric membranes for gas separation %A M.
