【摘要】 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。更多还原

【Abstract】 Aliphatic polyesters are the biodegradable materials with outstanding properties.They are synthesized via ring-opening polymerization catalyzed by metallic catalysts.The metal-free catalysts have been developed because the metallic residue contaminates the product especially in microelectronics and biomedical.The recent achievements reported with metal-free systems used in catalyzing ring-opening of lactide and functional monomer was focused.更多还原
