Abstract

Se describe un método para purificar un polipropileno recuperado. En una modalidad, el método involucra obtener polipropileno recuperado, poner en contacto el polipropileno recuperado con un primer disolvente fluido para producir un polipropileno recuperado extraído; después disolver el polipropileno recuperado extraído en un disolvente para producir una primera solución que comprende polipropileno. La primera solución se asienta y después se filtra. A partir de la solución resultante se separa un polipropileno más puro.
