Abstract

PROCEDIMIENTO PARA LA EXTRUSION DE COMPOSICIONES DE RESINA POLIOLEFINICA FORMADORA DE PELICULA. CONSISTE EN EXTRUIR UNA COMPOSICION QUE CONSTA DE UNA RESINA DE POLIOLEFINA DE CALIDAD DE PELICULA CATALIZADA SEGUN ZIEGLER-NATTA, QUE CONTIENE 5-500 PPM DE CLORURO Y 2-500 PPM DE ANTIOXIDANTE, EN PRESENCIA DE UN ACEPTOR DE ACIDO, A UNA TEMPERATURA COMPRENDIDA ENTRE 135<025>C Y 343<025>C. TIENE APLICACION PARA REDUCIR LOS FENOMENOS DE DEGRADACION OPTICA DE PELICULA DE POLIOLEFINA Y PARA IMPEDIR LA CORROSION DURANTE EL PROCESADO A ALTA TEMPERATURA.
