Abstract

Procedimiento para separar mezclas de plástico, a partir de una fracción o mezcla de plásticos poliolefínicos, por el cual el material de partida se pone en contacto con un disolvente y la temperatura de la mezcla disolvente-plástico se ajusta de tal modo, que se forma una solución con al menos un tipo de polímero disuelto, caracterizado porque el tipo de polímero disuelto se precipita de la disolución mediante cizallamiento, para separarlo de otros componentes de la solución.
