Abstract
Procedimiento de fabricación de tereftalatos de polimetileno altamente polimerizados, caracterizado por hacerse reaccionar un éster dialkílico de ácido tereftálico con un glicol de la serie OH (CH2)n OH en la que n es mayor que 1 sin exceder de 10, en presencia de un compuesto de metal alcalino-térreo, y el producto se somete luego a policondensación y, además, por hallarse también presente durante la reacción de policondensación, un compuesto de fósforo que es un ácido de fósforo, o un compuesto de fósforo que pueda convertirse en un ácido de fósforo sometido a las condiciones de reacción junto con un catalizador de policondensación.
