摘　　要：采用Matlab GUI工具，以单体组成为中间变量，依据共聚物组成方程及单体组成与转化率关系式，开发出一款用于绘制二元共聚合反应共聚物组成与单体转化率关系曲线的图形用户程序。通过对苯乙烯与甲基丙烯酸甲酯、丙烯腈与醋酸乙烯酯等共聚反应的应用表明：该图形用户程序界面友好，交互性强，适用性广，计算便捷，解决了绘制过程中共聚物组成与单体转化率关系式过于复杂而无法找到直接关系的困难，为预测不同竞聚率、不同投料比时共聚物组成与转化率的变化规律，控制共聚物组成，选择控制方法，验证实验，指导生产提供理论依据。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 the- oretical basis for predicting the variation of copolymer composition and conversion rate, controlling copolymer composition, selecting control method, verifying experiment and guiding production.
