由二氧化碳（CO2）和环氧化物合成的脂肪族聚碳酸酯是资源节约、高度生物相容性和可生物降解的聚合物。自1969年Inoue等人发现环氧化物和CO2的共聚反应以来，这已经成为在主要使用环氧丙烷和环氧环己烷（CHO）的化学合成中大规模利用CO2的重要和有用的技术。功能化聚碳酸酯是近几年才兴起的一个具有广泛应用前景的研究课题。本文综述了由CO2和功能性环氧单体合成的多种功能化聚碳酸酯的合成路线和性能。新材料和可能的应用，例如用于制药目的和膜的影响进行了审查。除了环氧乙烷和CHO衍生物为基础的聚碳酸酯，特别强调了缩水甘油醚为基础的聚碳酸酯的多种合成方法和后聚合改性。不仅提出了官能化的线性聚碳酸酯，而且还提出了各种新型聚碳酸酯结构，例如，星星和超支化聚合物。
Aliphatic polycarbonates synthesized from carbon dioxide (CO2) and epoxides are resource-saving, highly biocompatible and biodegradable polymers. Since the discovery of the copolymerization of epoxides and CO2 in 1969 by Inoue et al., this has become an important and useful technology for the large-scale utilization of CO2 in chemical synthesis, employing mainly propylene oxide, and cyclohexene oxide (CHO). Only in recent years, functionalized polycarbonates have become an emerging topic with a broad scope of potential applications. This review summarizes synthetic routes and properties of numerous functionalized polycarbonates synthesized from CO2 and functional epoxide monomers. Implications for new materials and possible applications, for instance for pharmaceutical purposes and membranes are reviewed. Besides polycarbonates based on oxirane and CHO derivatives, particular emphasis is placed on the manifold synthetic approaches and postpolymerization modifications of glycidyl ether based polycarbonates. Not only functionalized linear polycarbonates are presented but also a variety of novel polycarbonate architectures, e.g., star and hyperbranched polymers.
