脂肪族聚酯是一类具有良好性能的可生物降解高分子材料,有机金属催化也可用于催化交酯和内酯的开环聚合,但金属的残留会有不利影响,特别是在微电子和生物医用方面。因此提出非金属催化剂催化交酯和内酯的开环聚合,对非金属催化剂催化合成脂肪族聚酯的研究进展进行了综述,并提出了其在催化功能单体方面的优势。
Aliphatic polyesters are a class of biodegradable polymers with good properties. Organometallic catalysis can also be used to catalyze the ring-opening polymerization of lactides and lactones, but metal residues can have adverse effects, especially in microelectronics and Biomedical aspects. Therefore, it is proposed that the non-metallic catalysts catalyze the ring-opening polymerization of lactide and lactone, and the progress in the synthesis of aliphatic polyesters catalyzed by non-metallic catalysts is reviewed. The advantages of these catalysts in catalytic functional monomers are also proposed.
