Abstract According to copolymer composition equation and relation between monomer composition and conversion ratio by using the monomer composition as an intermediate variable, a graphical user program for plotting the relationship between copolymer composition and monomer conversion rate of two-component copolymerization was developed with the Matlab GUI as a tool. The application of copolymerization of styrene with Methyl methacrylate-Styrene (MMA-St), Acrylonitrile-Vinyl acetate(AN-VAc) can be demonstrated:This new graphical user program has friendly interface, strong interactivity, wide applicability and convenient calculation. It can solve the difficult problem that the relation between the composition of polymer and monomer conversion is too complex to find the direct relation in the process of drawing. It can provide theoretical basis for predicting the variation of copolymer composition and conversion rate, controlling copolymer composition, selecting control method, verifying experiment and guiding production.
