综述了可生物降解脂肪族聚酯和聚碳酸酯的酶催化合成和化学回收,以期建立绿色高分子化学。脂肪酶催化羟基酸、二酸与二醇、二酸酐与氧环烷、聚酸酐与二醇的缩聚聚合,或由小环到大环的内酯、环状二酯的开环聚合,生成相应的聚酯。此外,脂肪酶还催化碳酸二烷基酯与二醇的缩聚,以及环碳酸酯的开环聚合,生成相应的聚碳酸酯。这些聚酯和聚碳酸酯被脂肪酶选择性地降解为可再聚合的低聚物。这些使用酶的化学回收系统将建立一种可持续聚合物回收的新方法。最后,讨论了利用酶生产绿色聚合物的最新趋势。
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.
