A new constitute model is derived for the linear viscoelastic behavior of polymers under non-isothermal loading. The model extends the Tobolsky concept of adaptive links (entanglements) between polymeric molecules to thermoviscoelastic media. It permits the effect of temperature on elastic moduli (both current and limiting) and on the relaxation spectrum to be accounted for. According to the model developed, the stress tensor is expressed in terms of the strain tensor with the use of an integral constitutive equation. Coefficients of this equation and the kernel of the integral operator satisfy a system of partial differential equation. In the second part of this work, the model is applied for calculating residual stresses built-up in a thick-walled cylindrical shell under cooling from the rubber-glass transition temperature.
