Аннотация:The polymerization of composite materials in a plug-flow reactor is studied based on the theory of combustion. A two-temperature mathematical model of the self-sustained exothermic polymerization front in a monomer-filler mixture is developed with consideration given to the basic macrokinetic characteristics of the process, exothermicity of the chemical reaction, and heat transfer. The structure of the fields of temperature and concentrations of the reactants in the front is studied. The influence of special heat-transfer elements, preheating the feedstock supplied into the reactor, on the dynamics of the polymerization process and on the stabilization of the polymerization front is examined.
