通过开环易位聚合（ROMP）制备的可降解聚合物作为环境友好材料具有巨大的前景。然而，大多数ROMP单体衍生自石油资源，与生物质相比，石油资源通常被认为是较不可持续的。在此，我们提出了一种可降解聚合物的合成策略，通过利用交替的开环易位聚合的生物质基环烯烃单体，包括外氧杂降冰片烯和环烯醇醚。一个明确定义的聚（烯醇醚）的模块化结构，可调的玻璃化转变温度，并控制分子量的图书馆实现，证明了这种方法的多功能性。最重要的是，所得共聚物表现出高度的交替，使其主链在酸性条件下完全降解。
Degradable polymers made via ring-opening metathesis polymerization (ROMP) hold tremendous promise as eco-friendly materials. However, most of the ROMP monomers are derived from petroleum resources, which are typically considered less sustainable compared to biomass. Herein, we present a synthetic strategy to degradable polymers by harnessing alternating ROMP of biomass-based cyclic olefin monomers including exo-oxanorbornenes and cyclic enol ethers. A library of well-defined poly(enol ether)s with modular structures, tunable glass transition temperatures, and controlled molecular weights was achieved, demonstrating the versatility of this approach. Most importantly, the resulting copolymers exhibit high degrees of alternation, rendering their backbones fully degradable under acidic conditions.
