Polythioester exhibits some unique characteristics such as high melting point and poor solubility against various solvents. This report covers the synthesis of polythioester and its chemical recycling using the lipase-catalyzed reaction. The Tm and Tc of poly(11MU) were about 20 °C higher than those of the corresponding oxoester analogue. The obtained poly(HMU) was readily degraded by lipase CA in n-nonane to produce the corresponding cyclic oligomers having a molecular weight of few hundreds. These cyclic oligomers were also polymerized into poly(11MU). Chemical recycling of the polythioester using the enzyme can be expected from these results.
