The separation of olefin/paraffin mixtures using polymer–silver complexes is explored here. Composite membranes of 1:1 (CO/Ag) poly(2‐ethyl‐2‐oxazoline)/AgBF 4 on microporous polysulfone support are shown to facilitate the transport of propylene, with its permeance and pure gas selectivity over propane increasing 450‐fold when compared to pure polymer membranes.
