The controlled synthesis of block copolymers offers great potential for the valorization of biodegradable polyesters, many of which can be bioderived. Combining polyester blocks with other oxygenated polymers through ring-opening polymerization (ROP) and copolymerization (ROCOP) reactions allows for the synthesis of new materials with tunable properties. In this review article, we describe recent advances in the synthesis of diblock and multiblock polyesters, as well as polyether and polycarbonate block copolymers bearing biodegradable polyester block segments. Due to the great diversity of oxygenated monomers available from petrochemical and biomass sources, a great number of polymerization strategies have been developed involving metal- and organo-catalysts with different degrees of control. This review aims to provide an overview of the strategies available for the synthesis of different block copolymers: from the more widespread sequential addition methods to the more rare systems displaying high degrees of kinetic control in a mixture of monomers or those with controlled switchable behavior.

具有可生物降解聚酯链段的嵌段共聚物的合成策略

嵌段共聚物的受控合成为可生物降解的聚酯的增值提供了巨大的潜力，其中许多是可生物衍生的。通过开环聚合（ROP）和共聚（ROCOP）反应将聚酯嵌段与其他含氧聚合物结合使用，可以合成具有可调性能的新材料。在这篇综述文章中，我们描述了二嵌段和多嵌段聚酯以及带有可生物降解的聚酯嵌段链段的聚醚和聚碳酸酯嵌段共聚物的合成最新进展。由于可从石化和生物质来源获得的氧化单体种类繁多，因此已开发出许多聚合策略，其中涉及具有不同控制程度的金属和有机催化剂。
