摘　　要：聚酯多元醇作为合成聚氨酯的重要中间体,由多元酸与多元醇经酯化、脱水、聚合反应而成。简述了聚酯多元醇的分类及生产工艺,综述了其合成过程中的主要影响因素,并详细介绍了国内聚酯多元醇的研究进展,最后指出了未来聚酯多元醇的发展方向。As an important intermediate of polyurethane, the synthesis process of polyester polyol consists of esterification, dehydration and polymerization. The classification and production process of polyester polyols were briefly described. The main influencing factors in the synthesis of polyester polyols were reviewed and research progress in domestic polyester polyols was also researched in detail. In the end, the future research directions of polyether polyols were also pointed out.
