Abstract

Una proceso para producir polímeros de poliésteres porque comprende los pasos de: a) proveer un medio de polimerización que incluye dióxido de carbono;b) poner en contacto un monómero capaz de formar un polímero de poliéster con dicho medio depolimerización y c) polimerizar dicho monómero en dicho mediode polimerización. Asimismo, se provee una mezcla de reacción de polimerización que resulta conveniente para la preparación de un polímero depoliéster y los polímeros preparados. El proceso utiliza un medio de polimerización de dióxido de carbono que evita el uso de solventes orgánicosy permite la separación fácil del polímero de su medio de polimerización.
