Abstract
Ternary resin blends comprising a poly(biphenyl ether sulfone), a poly(ether sulfone) and a polysulfone, when molded, exhibit very attractive thermal and environmental resistance characteristics together with excellent mechanical properties. The molded articles comprising such ternary blends can be steam-sterilized repeatedly without stress cracking, and are not affected by corrosion-reducing additives such a morpholine.
