Abstract

Un dispositivo para el mezclado previo y la alimentacion de aditivos en una corriente de polímero fundido. El dispositivo presenta un elemento de conduccion 2, un primer y un segundo elemento intermedio 4a, 4b y una unidad de bombeo 6, de manera que la corriente de polímero fundido es conducida dentro de los canales 8; 10 del elemento de conduccion. El primer elemento intermedio 4a presenta un elemento de alimentacion 12, el cual se extiende dentro del primer canal 8 formando un canal anular. El elemento de alimentacion 12 se encuentra rodeado de bocas 14, a través de las cuales se succiona una parte del polímero fundido que va a ser mezclada dentro de la unidad de bombeo 6 con un aditivo. Esta mezcla se devuelve luego a la corriente de polímero fundido a través del elemento de alimentacion 12. El dispositivo del invento permite obtener tiempos menores de permanencia del polímero y está ligado a costos bajos.
