The nucleophilic conjugate substitution of α-(substituted methyl)acrylate is a very convenient reaction that occurs at ambient temperature with a variety of nucleophiles, such as amines, thiols, phenols, enols, and carboxylic acids. The reaction is quantitative when the nucleophile and leaving group have distinctly different acidities, whereas it becomes dynamic and reversible if their acidities are similar. This review describes the fundamentals and applications of conjugate substitution reactions in polymer chemistry. The nucleophilic conjugate substitution of α-(substituted methyl)acrylate is a very convenient reaction that occurs at ambient temperature with a variety of nucleophiles, such as amines, thiols, phenols, enols and carboxylic acids. The reaction is quantitative when the nucleophile and leaving group have distinctly different acidities, whereas it becomes dynamic and reversible if their acidities are similar. This review describes the fundamentals and applications of conjugate substitution reactions in polymer chemistry, particularly in monomer synthesis, end-group incorporation, end-functionalization, polycondensation, and main chain scission.

α-(取代甲基)丙烯酸酯在高分子化学中的共轭取代反应

α-(取代甲基)丙烯酸酯的亲核共轭取代是一种非常方便的反应,可在环境温度下与多种亲核试剂(例如胺、硫醇、酚、烯醇和羧酸)发生反应。当亲核试剂和离去基团具有明显不同的酸度时,反应是定量的,而如果它们的酸度相似,则反应是动态的和可逆的。这篇综述描述了共轭取代反应在聚合物化学中的基本原理和应用。α-(取代甲基)丙烯酸酯的亲核共轭取代是一种非常方便的反应,可在环境温度下与多种亲核试剂(如胺、硫醇、酚、烯醇和羧酸)发生反应。当亲核试剂和离去基团具有明显不同的酸度时,反应是定量的,而如果它们的酸度相似,则反应是动态的和可逆的。这篇综述描述了共轭取代反应在聚合物化学中的基本原理和应用,特别是在单体合成、端基结合、端基官能化、缩聚和主链断裂方面。
