The thermal disintegration of polymer materials under the effect of microwave radiation

According to Onsager potential transfer differential equation of irreversible process thermodynamics, the transfer potential of polymer materials radiated by microwave has been studied and the nonlinear Onsager potential in the materials is obtained. The results of this paper indicate that the generally used method of variable separation is not applicable in solving this problem so the method of limited integration variations is used, and the calculation corresponding to microwaves is relatively satisfied in comparison to the experimental measurement
