Title:
METHOD FOR THE PRODUCTION OF A TITANIUM CONTAINING CATALYST, TITANIUM CONTAINING CATALYST, METHOD FOR THE PRODUCTION OF POLYESTER AND POLYESTER
Document Type and Number:
WIPO Patent Application WO/2014/122070
Kind Code:
A1
Abstract:
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.
