Beschreibung
Zusammenfassung:	The present invention is directed to a method for the production of a titanium containing catalyst, wherein a titanium-(IV)-alkoxide of high purity is reacted with an alpha-hydroxy carboxylic acid. Furthermore the invention concerns a titanium containing catalyst allowing for the production of high viscosity polyesters with high thermal stability. In addition, the invention is directed to a method for the production of polyesters and polyesters themselves.
