有机硼催化四组分混合物一锅法合成聚缩醛-聚酯嵌段共聚物
Precision Synthesis of Polyacetal/Polyester Block Copolymers from a Four-Component Mixture Involving Epoxide Congeners via Switchable Polymerization
AI 导读
研究报道了一种可切换聚合策略，以有机硼为催化剂，从环氧化物、邻苯二甲醛（OPA）与纳迪克酸酐（NA）的四组分混合物出发，一锅法合成聚缩醛-聚酯嵌段共聚物。室温下只有端位环氧（PO）与 OPA 共聚形成聚缩醛段，内环氧（CHO）与 NA 保持惰性；加热后体系切换为 CHO/NA 共聚构建聚酯段。
推荐理由
在环氧单体与酐的四组分混合物中，用有机硼催化剂通过温度切换实现一锅法嵌段共聚，读者可了解正交化学选择性的动力学来源。
