The effect of ionomer structure on gas transport properties of membranes was investigated. For this purpose physical and transport properties of poly(phenylene oxide) (PPO) and its sulfonated derivative (SPPO) were compared. SPPO has a more rigid structure and a lower free volume, which determines l
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
Block copolymers of polysulfone-poly(alky1ene oxide)-poly(dimethylsi1oxane) have been prepared by the addition of preformed a,w-bis(hydrogensily1) poly(dimethylsi1oxane) oligomers to allyl end-capped poly(alky1ene oxide)-polysulfone. The hydrosilylation reaction, catalyzed by platinum, was employed
