Abstract
Un proceso continuo para preparar prepolimero de poliester que comprende los pasos de esterificar un diacido con un diol, hacer reaccionar el productoesterificado con un diol adicional y pasar el producto hacia abajo a traves de un reactor encol umna de contracorriente, mientras el gas inerte fluye haciaarriba a traves del reactor en columna. El producto prepolimero resultante tiene menor contenido de grupos de extremo acido respecto del materialesterificado.
