Abstract

PARA LA FABRICACION DE CUERPOS MOLDEADOS CON CELULOSA SE FORMA LA SOLUCION A PARTIR DE UNA SOLUCION DE CELULOSA EN OXIDO-N-METILMORFINA-N (NMMO) Y AGUA Y A CONTINUACION LA CELULOSA SE PRECIPITA EN UN BAÑO PRECIPITANTE QUE CONTIENE EL AGUA Y EL NMMO. SEGUN LA INVENCION LA TEMPERATURA DEL BAÑO PRECIPITANTE SUPONE, COMO MAXIMO, 0 GRADOS CENTIGRADOS; POR ELLO SE PUEDE ELEVAR LA CONCENTRACION DE NMMO EN EL BAÑO PRECIPITANTE SIN EMPEORAR LAS CUALIDADES DE LOS CUERPOS MOLDEADOS CON CELULOSA.
