提出了一种基于氮杂迈克尔加成和自由基光聚合的点击化学合成策略，通过三个时间控制步骤生成聚合物网络。伯二胺和二丙烯酸酯的选择允许发生两个连续的氮杂-迈克尔反应。该反应顺序提供了独特的机会来阻止自由基光聚合反应，提高交联密度。因此，第二个氮杂-迈克尔加成作为聚合物网络的有价值的后固结步骤出现。
A click chemistry synthetic strategy based on aza-Michael addition and radical photopolymerization is proposed to generate a polymeric network via three time-controlled steps. The selection of primary diamines and diacrylates allows two consecutive aza-Michael reactions to occur. This reaction sequence affords the unique opportunity to interpose a radical photopolymerization reaction, enhancing the cross-link density. Consequently, the second aza-Michael addition appears as a valuable postconsolidation step of the polymer network.
