Integrally skinned asymmetric flat sheet membranes were prepared from poly(2,6-dimethyl 1,4-phenylene oxide)(PPO) for CO 2 -CH 4 separation. Various experiments were carried out to identify PPO membranes, which have good mechanical strength and gas separation abilities. Membrane strength and selecti
Estimates for the thickness of the interface between poly (2,6-dimethyl-1,4phenylene oxide) (PPO) and copolymers of styrene-acrylonitrile (SAN) and styrenemaleic anhydride (SMA) based on the theory of Helfand and Tagami are compared to neutron reflectivity (NR) measurements. Good agreement is found
