A procedure for determining the relaxation constants of material that enter the Maxwell–Gurevich non-linear equation was examined. For recycled polyvinyl chloride, relaxation curves plotted at different temperatures were processed, and the influence of temperature on the relaxation parameters was investigated. For each parameter, an empirical formula was selected to describe its temperature dependence.
