Abstract
SE PRESENTA UN METODO PARA SEPARAR AL MENOS DOS COMPONENTES DE POLIMEROS TERMOPLASTICOS INMISCIBLES A PARTIR DE UNA MEZCLA LIQUIDA DE LOS MISMOS, EN DONDE EL PRIMERO DE AL MENOS DOS COMPONENTES DE POLIMEROS TERMOPLASTICOS INMISCIBLES TIENE UNA PRIMERA VISCOSIDAD EN ESTADO FUNDIDO Y EL SEGUNDO DE AL MENOS DOS COMPONENTES DE POLIMEROS TERMOPLASTICOS INMISCIBLES TIENE UNA SEGUNDA VISCOSIDAD EN ESTADO FUNDIDO, EN DONDE LA SEGUNDA VISCOSIDAD EN ESTADO FUNDIDO ES MAYOR QUE LA PRIMERA VISCOSIDAD EN ESTADO FUNDIDO, EN DONDE EL METODO COMPRENDE EL FLUJO DE LA MEZCLA LIQUIDA A TRAVES DE UNA ZONA DE CORTE, EN DONDE LA MEZCLA LIQUIDA SE EXPONE A LA FUERZA DE CORTE EN LA ZONA DE CORTE A UNA VELOCIDAD DE CORTE Y A UNA TEMPERATURA DE CORTE SUFICIENTE PARA SEPARAR AL MENOS DOS COMPONENTES DE POLIMEROS TERMOPLASTICOS INMISCIBLES EN FASES SUBSTANCIALMENTE DISCRETAS Y CONTINUAS, EN DONDE LA PRIMERA DE LAS FASES CONTIENE SUBSTANCIALMENTE EL COMPONENTE DE POLIMERO TERMOPLASTICO QUE TIENE LA PRIMERA VISCOSIDAD EN ESTADO FUNDIDO Y LA SEGUNDA DE LAS FASES CONTIENE SUBSTANCIALMENTE EL SEGUNDO COMPONENTE DE POLIMERO TERMOPLASTICO QUE TIENE LA SEGUNDA VISCOSIDAD EN ESTADO FUNDIDO. TAMBIEN SE SUMINISTRAN METODOS PARA RECICLAR UNA MEZCLA DE POLIMEROS LIQUIDOS UTILIZANDO EL METODO DE SEPARACION.
