Abstract

In a process for the production of a polyester without antimony, after transesterification with a manganese catalyst, it is blocked in the mol ratio P/Mn less than 1 by means of a phosphorus compound. 10 - 100 ppm Ge are used as a polycondensation mixed catalyst. The resulting antimony-free polyester is suitable for the production of bottles, films and filaments.
