Poly(ether ether ketone) (PEEK)/polysulfone (PSF) blends were obtained by kneading and compression moulding over the whole composition range. The blends were then both quenched and slowly cooled. Both cooling procedures provided blends with two practically pure phases and good small strain properties. Ductility was worsened, as expected, in slowly cooled blends. However, in quenched blends, which provided less phase‐separated fracture surfaces and no very different free volume, ductility showed unexpected good values which are tentatively attributed to common features of the chemical structure of both blend components.
