The deformation of three types of sulfone polymers—polysulfone (PSF), poly(ether sulfone) (PESF), and polyarylsulfone (PASF)—was performed with a mechanical testing system (MTS). The result and samples were studied using a transmission electron microscope (TEM), a dynamic mechanical analyzer (DMA), and a dielectric thermal analyzer (DETA). Stripes on TEM micrographs for small deformations increase with the fracture toughness ( G Ic ). The activation energy ( E a ) of the α‐transition was determined from DETA. The results show that both E a and TEM micrographs can be used to qualitatively estimate the order of G Ic of sulfone polymers. An energy model was proposed to explain this phenomenon.
