In this study polysulfone-poly(ethylene oxide) (PSF-PEO) random copolymers were synthesized using a polycondensation reaction via nucleophilic substitution. The PSF-PEO random copolymer membranes were prepared by varying PEO content in a glassy PSF matrix to see the effects of PEO segments on the ch
Two types of polyimide membranes; one crosslinkable and the other noncrosslinkable using ultraviolet light irradiation (UV irradiation), were prepared and investigated concerning the effect of UV irradiation on their gas permeabilities and selectivities. Permeability and diffusion coefficients for O
