Abstract
A new apparatus is described for measuring the permeability of polymer films to sulfur dioxide at partial pressures down to 2 Pa. It employs a permeation tube technique for establishing the partial pressure gradient and a detection system based on the absorption of light at 213.8 nm. Data on the permeability to sulfur dioxide of a range of polymer films are presented and discussed.
