Abstract : A poly (alkylsulfone) was prepared from an ethylene-propylene sulfide copolymer and from poly (ethylene sulfide). These polysulfones had no elastomeric properties. A commercial polysulfone thermoplastic molding resin and vinylidene fluoride/hexafluoropropene elastomer were blended in solution. A vulcanizate of the resulting material showed better retention of properties at elevated temperatures than did the fluorinated elastomer. Polysulfonates and polysulfonamides investigated were resins. (Author)
