Abstract
SE PROPONE UN DISPOSITIVO DE REACTOR PARA MEDIOS ALTAMENTE VISCOSOS Y CON CAPACIDAD DE FLUIR, EN PARTICULAR PARA POLIMEROS EN LA POLICONDENSACION DE POLIESTERES, QUE GARANTIZA UNA CALIDAD REGULAR SOBRESALIENTE DEL PRODUCTO DE REACCION CON UNA CONSTRUCCION RELATIVAMENTE SENCILLA Y UNA ESTABILIDAD MEJORADA CONTRA GIRO Y FLEXION DEL REACTOR. EL DISPOSITIVO DE REACTOR SE COMPONE DE UNA CARCASA (1) DISPUESTA EN UNA COLOCACION EN LA QUE SE DISPONE EN SU EXTREMO UNA ENTRADA (4) PARA LA AFLUENCIA DEL MEDIO Y EN EL OTRO EXTREMO UNA SALIDA (5) PARA LOS PRODUCTOS DE REACCION. DENTRO DE LA CARCASA (1) DEL DISPOSITIVO DE REACTOR SE APOYA DE FORMA GIRATORIA UN ROTOR (8). DE ACUERDO CON LA INVENCION EL ROTOR (8) MUESTRA UN CILINDRO (9) HUECO, QUE ESTA PROVISTO CON ROTURAS (10) Y ELEMENTOS (12,13) DE FORMA ANULAR PARA MOVIMIENTO Y TRANSPORTE DEL MEDIO. EL CILINDRO (9) HUECO SE SUMERGE PARCIALMENTE EN EL MEDIO CON CAPACIDAD DE FLUIR, CON LO CUAL LAS ROTURAS (10) DEL CILINDRO (9) HUECO SIRVEN PARA UNA MEZCLAADICIONAL DEL MEDIO.
