The dependence of the Grüneisen function of some polymeric materials on their density and temperature has been investigated. It is shown that in polymers having a complex macromolecular structure the temperature of the polymer vitrification varies depending on the rate of the effect exerted on them and, as a consequence, the relationship between the molecular and intramolecular values of the Grüneisen function undergoes a change. A comparative analysis of the results of calculations and experimental data is made. Their good agreement is obtained.
