| Abstract: | 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. |
