Abstract: Abstract The complex Young's modulus, E*(ω), and the complex strain‐optical coefficient, O*(ω), of poly(ether sulfone) (PES), polysulfone (PSF), and polyethermide (PEI), were measured over the frequency range 1 to 130 Hz. The data were analyzed with a modified stress‐optical rule: The Young's modulus was decomposed into two complex functions, E italicG*(ω) and E italicR*(ω); the modified stress‐optical coefficient, CR and CG, associated with the rubber (R) and glass (G) components, respectively, were determin…
