Effect of feed pressure and anion properties on facilitated olefin transport through solid polymer electrolyte (SPE) membranes containing silver ions in poly(2‐ethyl‐2‐oxazoline) (POZ) or poly(N‐vinyl pyrrolidone) (PVP) matrix has been investigated. Propylene solubility data in various SPE films are analyzed using the dual sorption model. The results indicate that the solubility coefficient of propylene in polymeric matrices was unexpectedly high although it was unmeasurably low in corresponding pure polymer. The equilibrium constants of the reaction between carrier and propylene for SPE films containing AgBF 4 are higher than those with AgCF 3 SO 3 for both polymers investigated. In addition, saturated amounts of propylene coordinated to the silver ions in SPE films with AgBF 4 are higher than those with AgCF 3 SO 3 , resulting in higher propylene permeance in polymer electrolytes containing AgBF 4 .
