Mathematical Modelling of the Copolymerization of Styrene with Maleic Anhydride in a Homogeneous Environment

Igor Grigoryev, Eldar Miftakhov and Svetlana Mustafina

In this paper, a mathematical model based on the kinetic scheme of the copolymerization of styrene and maleic anhydride was built. The mathematical model is a system of ordinary differential equations whose dimension tends to infinity, because of the infinite number of the reaction components. Applying the method of statistical moments, infinite system of ordinary differential equations is reduced to a system with a finite number of equations and becomes solvable. Numerical solution of the target system to determine the average molecular properties such as number average and weight average molecular weights and polydispersity index.
