Abstract

Un proceso para preparar un polímero modificado por extraccion de una corriente de escape de polímero fundido de la línea de descarga de un reactor de polimerizacion continuo, mezclado de un aditivo polimérico altamente modificado en un polímero fundido dentro de la corriente de escape, luego introduccion de la corriente de escape que contiene un modificador en forma tardía en el proceso de fabricacion antes del punto de extraccion de la corriente de escape. Los procesos mejorados de la invencion tienen particular utilidad para procesos a gran escala, con reactor continuo donde las transiciones y corridas de produccion cortas son economicamente prohibitivas, limitando por lo tanto el rendimiento del producto. El proceso es particularmente adecuado para producir una familia de copoliésteres mediante un proceso de produccion de fase fundida.
