摘要
聚碳酸酯二元醇(PCDL)是制备聚碳酸酯型聚氨酯的重要原料,和传统的聚醚型聚氨酯和聚酯型聚氨酯相比,聚碳酸酯型聚氨酯表现出优异的耐水解性、力学性能和生物相容性。随着聚氨酯需求量的增长,聚碳酸酯二元醇的研究受到行业内的高度重视。本文先简要介绍了PCDL的合成方法,重点回顾了近十年来用于酯交换缩聚法制备PCDL的催化剂的研究进展,简述了PCDL在聚氨酯工业中的应用。未来开发非均相催化剂及高沸点的有机碱催化剂、制备不同结构的聚碳酸酯二元醇是PCDL的主要研究方向。
Polycarbonate diols（ PCDL） is an important raw material for the synthesis of polycarbonate-based polyurethane. Compared with traditional polyether-or polyester-based polyurethane,the polycarbonate-based polyurethane shows better hydrolytic resistance,mechanical properties and superior antistatic biocompatibility. With the increasing demand of polyurethane,the research on PCDL has got more and more attention. In this paper,the synthesis methods of PCDL were introduced briefly,and then the catalysts for the transesterification method in last decades were reviewed in detail. Moreover,the application of PCDL in polyurethane industry was also introduced. In the future,it should pay more attention to the heterogeneous catalyst or organic base catalyst with high boiling point and the preparation of PCDL with diverse structures.
