A mathematical model of the process of thermal destruction of polymer binders has been developed, taking into account experimentally established dependences of the decomposition depth on temperature and the amount of coke residue on the heating rate. A method for determining the kinetic parameters of the process by the method of inverse problems has been developed. Kinetic parameters of the model for six binders are determined.
