摘要:: 利用二氧化碳与环氧化物的共聚反应合成二氧化碳共聚物，进而制备出具有生物降解性能的二氧化碳基塑料或二氧化碳基聚氨酯等高分子新材料，正在成为绿色高分子化学和化工的重要组成部分，更是高分子学术界和产业界践行国家碳中和战略的前沿热点。在所有的二氧化碳共聚物中，二氧化碳与环氧丙烷的共聚物聚碳酸丙烯酯（poly(propylene carbonate),PPC）最受关注，也是工业化成熟度最高的品种。基于笔者课题组和国内外研究团队的工作，总结了PPC的合成方法、材料性能与产业化进程，着重探讨PPC在低成本生物降解塑料、环保型聚氨酯等领域的广泛应用，并预测了其未来发展趋势。

Abstract:: The copolymerization of carbon dioxide and epoxides affords CO2 copolymers, which can be escalated to commodity new materials like biodegradable plastics or polyurethane elastomers, constituting a significant advance of green polymer chemistry and chemical engineering. The CO2 copolymers research is a frontier hotspot in the polymer field fulfilling the national initiative of carbon neutrality. Among all CO2 copolymers, poly(propylene carbonate) (PPC), a copolymer from carbon dioxide and propylene oxide, is receiving most concerns both from academic and industry. Based on the recent progress in our group as well as in worldwide CO2 copolymer research community, this review summarizes the synthesis, material properties and industrialization of PPC, highlights the widespread applications of PPC in the fields of low-cost biodegradable plastics and sustainable polyurethanes. Finally, a perspective on new materials based on CO2 copolymer is addressed.
