Making polymers from CO₂ and olefins has been long sought and is of particular significance for chemical utilizations of CO₂. Herein, high molecular-weight polymers with 29 wt % CO₂ were obtained by polymerizing a δ-lactone (L) synthesized from a C–C coupling reaction between CO₂ and 1,3-butadiene, an economical large-volume chemical that can also be derived from top biomass platform chemicals. Although L has been known for many years, little was investigated in its polymerization. We found that L’s polymerizability can be vitalized upon simply heating in the presence of O₂. The polymerization is additive/solvent-free with abundant preserved olefins and up to full monomer conversion, providing a convenient, economical, and scalable avenue to obtain CO₂-derived polymers with potentially tailorable properties via the readily modifiable olefins.

由 CO2/1,3-丁二烯衍生的内酯高效合成功能化聚合物

长期以来一直在寻找由 CO ₂和烯烃制造聚合物，并且对于 CO ₂的化学利用具有特别重要的意义。_{在此，通过聚合由 CO 2}和 1,3-丁二烯之间的 C-C 偶联反应合成的 δ-内酯 ( L_{) 获得了具有 29 wt % CO 2}的高分子量聚合物，这是一种经济的大体积化学品，可以也来源于顶级生物质平台化学品。尽管L已为人所知多年，但对其聚合的研究却很少。我们发现L的聚合性可以通过在 O _{2存在下简单加热来激活}. 该聚合反应不含添加剂/溶剂，具有丰富的保存烯烃和高达完全的单体转化率，为通过易于改性的烯烃获得具有潜在可定制性能的CO _{2衍生聚合物提供了一种方便、经济且可扩展的途径。}
