Abstract

The disclosed invention relates to a composition comprising a crosslinked blend of polyphosphazene polymers. The composition comprises a first polyphosphazene and a second polyphosphazene, where the first polyphosphazene and the second polyphosphazene being bound by a thiol bearing crosslinking agent. Such compositions are useful as a membrane material for the separation of gasses in a gaseous mixture.
