Gas and vapor permeability of perfluoroalkylated polymers

Polymer Bulletin Aims and scope Submit manuscript

Summary

Three polymers bearing benzene rings: polystyrene, poly(2,6-dimethyl-p-phenylene oxide) and poly(diphenylacetylene), were chemically modified with bis(heptafluorobutyryl) peroxide. The heptafluoropropylated products have higher gas permeabilities than the parent polymers. In the pervaporation of aqueous ethanol, modified poly(diphenylacetylene) showed ethanol permselectivity.
