摘要
在高分子化学的本科教学中,几乎都使用缩聚作为逐步聚合的教学案例,虽然这基于缩聚与逐步聚合二者之间密切的联系,但容易让学生混淆这两个聚合概念,不利于二者的区分。为此本文提出了一个可以作为逐步聚合教学的新案例——巴比耶聚合。有别于本科教学中基于缩合反应的逐步聚合,巴比耶聚合是一种基于加成反应的聚合方法,具有逐步特征。通过引入巴比耶聚合作为逐步聚合的教学新案例,可以加深学生对逐步聚合的理解,避免将逐步聚合等同于缩聚,有助于学生更好地对缩聚和逐步聚合概念进行区分。
In the teaching of undergraduate Polymer Chemistry courses,polycondensation is commonly used as a teaching case of step-growth polymerization.While there is a close relationship between polycondensation and stepgrowth polymerization,this approach may cause confusion between these two polymerization concepts.This article proposes a new teaching case for step-growth polymerization,i.e.,Barbier polymerization.Unlike traditional stepgrowth polymerization cases based on condensation reaction,Barbier polymerization is based on addition reaction and exhibits the characteristics of step-growth polymerization.The introduction of Barbier polymerization as a new teaching case for step-growth polymerization can help students understand step-growth polymerization in depth and avoid confusions in the basic polymerization concepts of polycondensation and step-growth polymerization.
