Abstract
PURPOSE. The processes of radical polymerization of methyl methacrylate are subjected to a strong gel effect and in this connection the polymerization process is carried out at a relatively low temperature and a high ratio of a monomer and water, which negatively affects the productivity of reactors. The purpose of this publication is to study the dynamic features of a typical industrial reactor under various process conditions for the further development of a control system for such reactor. METHODS. In order to obtain the transfer function of the control object our previous work provided a mathematical description of the reactor in the form of a system of differential equations of heat balance and a structural diagram of the control object. Using Mathcad and MATLAB Simulink, this article shows the variation ranges of all parameters of the control object depending on the degree of monomer conversion under different flow conditions of the process. RESULTS. A family of transient response curves of the control object is obtained under different flow conditions of the process. CONCLUSIONS. The obtained results correspond to the real data of polymethyl methacrylate production at industrial enterprises.
