Abstract

Se trata de un procedimiento donde en una primera etapa se preparan ésteres u oligoésteres en presencia de catalizadores de titanio, luego policondensadosen presencia de catalizadores preparados por precipitacion hidrolítica simultánea de compuestosde titanio y de compuestos de un metal seleccionado del grupoIA, IIA, VIIIA, IB, IIB, IIIB o IVB del sistema periodico, siendo el compuesto de titanio y el compuesto metálico, de dicho metal, independientemente uno deotro, alquilato, alcoholato o carboxilato de titanio y siendo > 50 : 50 mol/mol la relacion molar del compuesto de titanio al compuesto metálico. También sepropone la utilizacion de dichos catalizadores para los propositos mencionados.
