Qiu-lian LI, Ya-qin DING, Jin-lan ZHOU, Cheng-mei LIU. The Educational Pratice of Determination of Monomer Reactivity Ratio in Copolymerization NMR Detection[J]. Polymer Bulletin, 2019,32(11):69-72.
The experiment is used NMR to determinate the reactivity ratio of the copolymerization reaction between styrene and methacrylate. Through the experiment teaching students mastered the method of the influence on the reactivity ratio with temperature changing. Students ability of connecting theory with practice is improved and abstract theory is actualized.Moreover it would be expanding students' vision and thinking. It also increased the interesting of the experiment and optimized the teaching method and curriculum system. In the end it produced good teaching results as well.
