The free volume behaviour of the polyacrylonitrile/lithium triflate system is investigated over the composition range 0 -75 wt % salt. The addition of salt, up to 45 wt %, to the PAN polymer substantially increases the free volume as measured by the orthopositronium pickoff lifetime, 3 . Beyond this
