Abstract

La invencion pertenece a nuevos sistemas catalizadores para las reacciones de policondensacion, por ejemplo, parar producir tereftalato de polietileno. De acuerdo con la invencion, los compuestos complejos con estructuras de hidrotalcita-analogas de la formula general [M( II)1- xM(III)x(OH)2]x+(An-xn)mH2O,se utilizan, en donde M(II) representa los metales divalentes, preferentemente Mg o Zn o NI o Cu o Fe(ll) o Co, y M(III) representa los metales trivalentes, por ejemplo Al o Fe(lll), y A representa los aniones, preferentemente carbonatos o boratos. Estos catalizadores pueden calcinarse y pueden utilizarse en combinacion con los compuestos de fosforo que contienen al menos un enlace de fosforo- oxigeno hidrolizable.
