Design and Construction of Virtual Simulation Experiment for Anionic Polymerization of Styrene
Anionic polymerization is an important knowledge point in the course of Polymer Chemistry,which has certain applications in industrial production.However,the quality of experimental teaching is difficult to achieve because the traditional teaching process of polymer chemistry experiments is limited by the flammability and explosiveness of n-butyl lithium,the condition of the'anhydrous and anaerobic'experiments,and the number of large instruments.The lack of anion polymerization experiments makes it difficult for students to fully understand and master relevant theoretical knowledge,enrich their basic skill training,and improve their ability to solve practical problems,which is very detrimental to the improvement of their overall quality.For this purpose,this article designs and constructs a virtual simulation experiment project for styrene anionic polymerization,including four experimental modules:raw material treatment,styrene anionic polymerization,determination of polystyrene molecular weight,and expansion of anionic polymerization applications.Using virtual simulation technology to realistically reproduce experimental phenomena and reaction processes,students can repeatedly practice interactive operations,master the key points of'anhydrous and anaerobic'experimental operation,the principle of anion polymerization reaction and experimental precautions,achieving teaching effects similar to real experiments.
