Some aspects of polymer friction are considered, the need to take into account the specific properties of polymeric materials (temperature-time dependence of deformation characteristics, influence of supramolecular structures, etc.) is shown. ). The solution of the problem of forming the actual area of metal-polymer contact is given, the role of structural transformations in the process of polymer friction is shown, methods and devices used in experimental studies are described. The possibility of applying the obtained results in the calculation and design of metal-polymer friction nodes . The book is intended for scientific and engineering workers specializing in the research and application of polymer materials .
