摘　　要：介绍了聚酯催化剂中锑、锗、钛三个系列的各自特点, 综述了复合型钛系和超细TiO2 型聚酯催化剂的最新进展, 认为新型钛系催化剂催化活性更高, 更环保, 而且用它合成的聚酯产品色相好, 热稳定性得到了改善。The features of Sb, Ge, and Ti system polyester catalysts were presented. The recent development of study on multiple Ti catalysts and superfine TiO 2 catalysts used in polycondensation reaction of polyester was introduced in detail. These two types of Ti system catalysts had much higher catalytic activities, and were environmentallyfriendly . At the same time, the color and thermal stability of the polyester produced could be improved by using these catalysts in reaction.
