“…[133] The copolymers of trimethylene carbonate with other monomers have been used in the field of biomedical applications, such as sutures with improved flexibility [134] and drug-delivery systems. [135] Polycarbonates, being alkyl or aryl esters of carbonic acid, can be obtained by the direct or indirect application of the phosgenation process. However, this process uses extremely hazardous phosgene, thus a more convenient process is now needed.…”

This article summarizes the enzyme‐catalyzed synthesis and chemical recycling of biodegradable aliphatic polyesters and poly(carbonate ester)s directed towards establishing green polymer chemistry. Lipase catalyzes the condensation polymerization of a hydroxy acid, diacid with diol, diacid anhydride with oxirane, and polyanhydride with diol, or the ring‐opening polymerization of lactones of small to large rings, and a cyclic diester to produce the corresponding polyesters. Also, lipase catalyzes the condensation polymerization of a dialkyl carbonate with diol, and the ring‐opening polymerization of a cyclic carbonate to produce the corresponding polycarbonates. These polyesters and polycarbonates were selectively degraded by lipase to produce repolymerizable oligomers. These chemical recycling systems using an enzyme will establish a novel methodology for sustainable polymer recycling. Finally, current trends in green polymer production using enzymes are discussed.

“…[2] It is well known that copolymerization is an effective way of providing materials with different properties. The properties of PTMC also can be tailored by copolymerization of trimethylene carbonate (TMC) with other cyclic monomers, such as glycolide, [3] lactide, [4] e-caprolactone, [5] 1,4-dioxan-2-one, [6] cyclic phosphates, [7] as well as other cyclic carbonates, [8] in order to meet different needs.…”
