Abstract

Para la preparacion de poliésteres y copoliésteres se proponen, como catalizadores de policondensacion, coprecipitados de dioxido de titanio/dioxido de silicio con una composicion de TiO2:SiO2 = 90:10 hasta 20:80 mol/mol, y/o coprecipitados de dioxido de titanio/dioxido de zirconio con una composicion de TiO2:ZrO2 = 95:5 hasta 70:30 mol/mol. Estos muestran una actividad catalitica más alta que el Sb2O3 por lo que la cantidad añadida preferida es de solamente 10 a 100 ppm, referida a los ésteres u oligoésteres a policondensar.
