摘　　要：聚酯钛系催化剂催化活性高,对环境友好,能够使PET具有更高亮度和透明性,但也具有催化稳定性差、加剧副反应,使合成的PET色相变差、性能指标下降等缺点。通过对国外的一些钛系催化剂产品和对国内学者的钛系催化剂应用研究的简要说明,介绍了PET钛系催化剂应用发展的现状。随着聚酯工业的发展以及人们的环保意识的提高,具有高反应活性的不含重金属的钛系催化剂的开发应用,目前已经成为聚酯缩聚催化剂发展的趋势,有着光明的应用前景。The Ti catalysts in PET have much higher catalytic activities and without heavy metal ion and be friendly to environment, but Ti catalysts production had bad stability, aggravated the subsidiary reactions, yellow colour and inferior quality etc. The development survey and the new developments of Ti catalysts in PET production are introduced. The high efficiency type of new Ti catalysts have a good trend in development. With the development of polyester industry, the improved environment and heath awareness, new type Ti catalysts with high reactivity have a wide development prospect.
