| Abstract: | One of the most important problems of the theory of processing polymer materials is the investigation of the flow of thermoplasts in the region of deformation of rolling machines. In this paper, an analysis is carried out of this process, based on equations for an anomalously viscous liquid, including the energy equation in the bipolar system of coordinates. An analytical solution is given for this system of equations, and also given are the results of the solution obtained by numerical methods of analysis, taking account of the dependence of the rheological coefficients on the temperature. The dependence of the maximum temperature rise in the region of deformation on the speed of rotation of the rollers, the coordinates of the material feed in the region of deformation, and the rheological coefficients, is investigated.Translated from Izvestiya Akademii Nauk SSSR, Mekhanika Zhidkosti i Gaza, No. 2, pp. 17–24, March–April, 1976.In conclusion, the authors thank S.
