Abstract
Un método para reciclar residuos que contienen poliolefina usando un disolvente que tiene un parámetro Hansen específico y poner en contacto esta mezcla con un auxiliar de filtración líquido antes de separar la poliolefina de la mezcla. El método comprende las siguientes etapas: mezclar el reciclar el residuo que contiene poliolefina con un disolvente que tiene un parámetro de Hansen dH de 0,0 a 3,0 MPa¹/²; poner en contacto esta muestra con un auxiliar de filtración líquido que tienen un parámetro de Hansen dH > 4,0 MPa¹/²; y separar la poliolefina de la mezcla.
