Abstract

PROCEDIMIENTO PARA LA PREPARACION DE MASAS FUNDIDAS DE POLIMEROS QUE ESTAN SUSTANCIALMENTE EXENTAS DE COMPONENTES VOLATILES, PARTIENDO DE MASAS FUNDIDAS DE POLIMEROS DE ALQUENOS MUY VISCOSAS QUE CONTIENEN DISOLVENTES Y RESIDUOS DE MONOMEROS. CONSISTE EN TRATAR UNA MASA FUNDIDA DE POLIMEROS DE ALQUENOS CON UN INDICE DE FUSION MENOR DE CUATRO Y CON UN CONTENIDO DE COMPONENTES VOLATILES MENOR QUE UN 10%, EN UN EXTRUSOR DE DESGASIFICACION ENFRIADO QUE TIENE UNA ZONA DE AMASADO CON ACUMULACION DE PRESION Y UNA ZONA DE DESGASIFICACION A PRESION REDUCIDA, DE FORMA TAL QUE SE APLICA UN INTENSO ENFRIAMIENTO EN LA ZONA DE AMASADO, MIENTRAS QUE ES MENOS INTENSO EL ENFRIAMIENTO O CALENTAMIENTO EN LA ZONA DE DESGASIFICACION.
