• Non-equilibrium thermodynamics is applied to linear volume viscoelasticity of amorphous polymers. A relation describing the motion of polymer chain is derived, which is essentially equivalent to that of Bueche. The present method generalizes the random spring model for the bulk system. The relaxation spectrum obtained for the isothermal complex bulk modulus in the low frequency region has the same shape as the shear modulus. It shows a characteristic slope of (-1/2) in the log-log plot of the relaxation spectrum. Furthermore, the real part of isothermal complex compressibility depends closely on the free volume change. The calculated ratio of the imaginary part of the complex bulk modulus to that of the shear modulus agrees with the experimental data given by Wada et al. for styrene-butadiene rubber in the low frequency region.
