将可再生资源转化为功能性和可降解的聚合物是由不断增长的取代不可持续的聚烯烃的需求推动的。然而，许多可降解均聚物的用途仍然有限，因为它们的性能比商品聚烯烃差。因此，用一锅法合成序列定义的共聚物不仅在化学上具有概念上的吸引力，而且通过最大化材料利用率和改善聚合物的性能在经济上也具有吸引力。在许多聚合策略中，环状单体的开环(Co)聚合可以有效地获得相对分子质量和相对分子质量分布得到高度控制的可降解聚合物。在这里，我们重点介绍了在使用结合多个催化循环的单一催化系统实现环状单体混合物的一锅顺序控制聚合方面的最新进展。给出了这类顺序控制开环共聚的环状单体、催化剂和聚合机理的范围。
Transforming renewable resources into functional and degradable polymers is driven by the ever‐increasing demand to replace unsustainable polyolefins. However, the utility of many degradable homopolymers remains limited due to their inferior properties compared to commodity polyolefins. Therefore, the synthesis of sequence‐defined copolymers from one‐pot monomer mixtures is not only conceptually appealing in chemistry, but also economically attractive by maximizing materials usage and improving polymers’ performances. Among many polymerization strategies, ring‐opening (co)polymerization of cyclic monomers enables efficient access to degradable polymers with high control on molecular weights and molecular weight distributions. Herein, we highlight recent advances in achieving one‐pot, sequence‐controlled polymerizations of cyclic monomer mixtures using a single catalytic system that combines multiple catalytic cycles. The scopes of cyclic monomers, catalysts, and polymerization mechanisms are presented for this type of sequence‐controlled ring‐opening copolymerization.
