The fluctuation theory indicates that the isotropic light scattering loss of amorphous polymer glass, which is used as a material for polymer optical fiber, decreases with the decrease in isothermal compressibility β and refractive index. In order to prepare low light-scattering-loss polymer glass, it is necessary to know the isothermal compressibility of polymers. However, the β for most polymers has not yet been measured precisely using a mechanical procedure. In this work, we estimate the isothermal compressibility of amorphous polymer glass from its molecular structure and calculate its isotropic light scattering loss.
