Abstract:
A poly(aryl ether sulfone) of low polydispersity containing no detectable cyclic polymer byproduct was prepared by melt polymerization without catalyst, solvent, and base. The poly(aryl ether sulfone) can be used without further purification for the manufacture of articles. A melt composition for fabricating an article comprises the poly(aryl ether sulfone) and, optionally, one or more additives.
