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 step-growth 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 step-growth 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.
