Abstract
LOS POLIMEROS, TALES COMO ETERES POLIFENILENO, SON AISLADOS DE LA SOLUCION EN UN EXPULSOR POR ADICCION DE AL MENOS UN NO-SOLVENTE. LOS PASOS OPCIONALES INCLUYEN QUITAR LOS VOLATILES A TRAVES DE VENTANAS O PUERTAS EN EL EXPULSOR, Y EMPLEANDO UN NO-SOLVENTE AUXILIAR. LAS OPERACIONES ADICIONALES, TALES COMO MEZCLAR CON OTROS POLIMEROS, FRACCIONAMIENTO DE MOLECULAS DE PESO MOLECULAR BAJO, Y LA FUNCIONALIZACION POR REACCION QUIMICA, DEBEN TAMBIEN SER REALIZADAS EN EL EXPULSOR.
