Abstract

La presente invencion describe un proceso para la polimerizacion de tereftalato de politrimetileno por esterificacion de acido tereftalico o tereftalato de dimetilo con 1,3-propan diol, precondensacion del producto de esterificacion para producir un producto de precondensacion, y policondensacion del producto de precondensacion para producir tereftalato de politrimetileno y, como un subproducto, el dimero ciclico de acido tereftalico o tereftalato de dimetilo y 1,3-propan diol, que comprende: (a) recuperar el dimero ciclico de la polimerizacion, (b) hacer reaccionar de 0.5 a 2 5 por ciento en peso del dimero ciclico en 1,3-propan diol en presencia de 0.1 a 10 por ciento en peso del dimero ciclico de un catalizador basico durante cinco minutos a 24 horas de 50 a 210¦C, (c) neutralizar opcionalmente el catalizador basico en el producto de reaccion de (b), y (d) recircular el producto de reaccion en el proceso de polimerizacion.
