AnnotationIn this article the mechanism of radical copolymerization of $\alpha$-methylstyrene with maleic anhydride in a heterogeneous medium is studied. A copolymer of $\alpha$-methylstyrene and maleic anhydride was prepared in an aromatic solvent-benzene using an initiator-azodiisobutyronitrile. The conditions for the copolymerization of $\alpha$-methylstyrene with maleic anhydride are selected. Based on the mechanism of radical copolymerization of $\alpha$-methylstyrene with maleic anhydride, a mathematical model of the process is constructed, which allows to study the process, to study the dynamics of concentrations of reacting substances in a heterogeneous medium and to predict the properties of the product.
