Abstract
LA EFICIENCIA DE REDISTRIBUCION DE UN CATALIZADOR DURANTE LA REDISTRIBUCION DE POLICARBONATOS, SE MEJORA EMPLEANDO UN DISEÑO DEL TORNILLO DEL EXTRUSOR, QUE PROPORCIONA UN SELLADO FUSIONABLE ENTRE LA GARGANTA DEL EXTRUSOR Y LA ABERTURA DE VACIO. SE PRODUCE UN SELLADO FUSIONABLE, CUANDO EL VOLUMEN LIBRE EN EL INTERIOR DEL EXTRUSOR ESTA SUFICIENTEMENTE LLENO DE RESINA FUNDIDA, DE FORMA QUE SE EVITA EL PASO DE GASES ENTRE LAS SECCIONES DEL EXTRUSOR.
