报道了一种基于逆电子需求狄尔斯-阿尔德反应的新型高效聚合物后聚合改性平台。由烯丙基缩水甘油醚和缩水甘油通过阴离子开环聚合合成了明确的聚合物，并用许多带有从羧酸盐和酯到伯胺的官能团的四嗪衍生物进行后聚合改性。通过实时 H-1 NMR 和 GPC 进行的聚合动力学分析表明，在有机溶剂和水溶剂中，侧链转化率快速且高度高 (>95%)，并生成明确的功能聚合物，且无需添加剂或催化剂。
A new and highly efficient polymer, post polymerization, modification platform based on an inverse electron demand Diels-Alder reaction is reported. Well-defined polymers were synthesized from allyl glycidyl ether and glycidol by anionic ring-opening polymerization with postpolymerization modifications conducted with a number of tetrazine derivatives that carried functional groups spanning from carboxylates and esters to primary amines. Analysis of polymerization kinetics by real-time H-1 NMR, and GPC revealed a rapid and high degree of side-chain conversion (>95%), with the generation of well-defined functional polymers, in both organic and aqueous solvents, without the need for additives or catalysts.
