Characterization of high-temperature poly(ether sulfone) (HTPES) molar mass was performed using light scattering, viscometry and size-exclusion chromatography (SEC). In pure Nmethyl-2-pyrrolidone (NMP), a large increase of the reduced viscosity at low concentration was observed. By addition of a sal
