Abstract

LA invención se refiere a un procedimiento para la preparación de poliéster es resorvibles mediante la polimerización en masa, fundiéndose y homogeneizándose los componentes de la reacción en un reactor de agitación, seguidamente la mezcla de reacción se transfiere a varios recipientes de menor volumen, se termina de polimerizar la mezcla de reacción en estos recipientes y se aísla el poliéster obtenido mediante su retirada de los recipientes, así como al uso de los policsteres resorvibles así preparados para la fabricación de implantes resorvibles.
