共存于平衡体系中

参与反应物质的电子效应对平衡体系稳定性至关重要。只有稳定的平衡体系、以及活性种与休眠种的快速可逆变化才是活性聚合的保障。认识到这些

有助于学生们加深对活性聚合本质的理解

并能够对知识灵活应用。

Abstract

Several typical living free-radical polymerization (LFRP) systems were studied

the electronic effects of active species and dormant species on the equilibrium systems were analyzed

and the essential reasons for the occurrence and control of LFRP were investigated. It was concluded that active species and dormant species coexist in equilibrium system; The electronic effect of the materials was significant for the equilibrium systems ; Stable equilibrium systems and the rapid reversible changes between active species and dormant species resulted in the living free-radical polymerization. Recognizing this principle was helpful for students to understand the nature of living free-radical polymerization

and to use the knowledge smartly.
