Abstract
LOS PESOS MOLECULARES (MW Y MN) Y LA POLIDISPERSION (MW/MN) DE UN POLIMERO TIENE IMPACTO SIGNIFICATIVO SOBRE LAS PROPIEDADES DEL PRODUCTO FINAL Y LA PROCESABILIDAD DE LOS MATERIALES. ESTE INVENTO OFRECE UN METODO PARA UNA PREDICCION EN LINEA DE LAS PROPIEDADES DE UN POLIMERO. EN UN REACTOR DE POLIMERIZACION CONTINUA EN EL QUE TIENE LUGAR UNA REACCION DE POLIMERIZACION IRREVERSIBLE, LOS CENSORES OFRECEN LA TEMPERATURA AXIAL Y EL PERFIL DE PRESION EN EL REACTOR ASI COMO LAS VELOCIDADES DE FLUJO DE MONOMERO Y LA CONCENTRACION PARA DETERMINAR MW, MN Y LA POLIDISPERSION. BASADO EN UN ANALISIS MECANICO DE FLUIDOS NO NEWTONIANOS, EN UN ANALISIS DE INFLUJO DIFERENCIAL DE UNA INCORPORACION DE FLUJO LATERAL Y EN LA DETERMINACION DE LOS MOMENTOS DE LA DISTRIBUCION DE PESO MOLECULAR MEDIANTE UN ALGORITMO DE NEWTON-RAPHSON, EL MODELO CALCULA UN PERFIL DE LAS PROPIEDADES DEL POLIMERO AXIAL. LA "MEDICION ANALITICA" DE TIEMPO REAL EN LINEA DE LAS PROPIEDADES DE UN POLIMERO SE UTILIZAN PARA ALERTAR AL OPERADOR DE POSIBLES PROBLEMAS INUSUALES EN EL REACTOR, PARA OPTIMIZAR EL FUNCIONAMIENTO DEL REACTOR DURANTE EL ARRANQUE O LA DESACTIVACION O DURANTE LOS CAMBIOS DE VELOCIDAD. ESTO PERMITE LA CORRELACION DE LAS PROPIEDADES DEL POLIMERO PARA EL RENDIMIENTO DEL PRODUCTO EN LOS PROCESOS DE FLUJO DESCENDENTES-
