Abstract

The article presents a theoretical analysis of the possibility of the formation and behavior of short-lived transformation structures in polymeric materials under conditions of high input energy densities, typical of the dynamic contact zone of the tool composite with the processed material. The role of spin relaxation processes in the formation of characteristic response times of polymeric materials to intensive energy input is shown. The features of the dynamic behavior of polymeric structures under the mentioned conditions are considered. The possibility of determining the characteristic time that determines the rate of energy exchange between the electronic and vibrational subsystems of the polymer bond using the NMR method is shown.
