Abstract

PROCESO DE OBTENCION DE POLIOLEFINAS CON DISTRIBUCIONES DE PESOS MOLECULARES ANCHAS, BIMODALES O MULTIMODALES. EL PROCEDIMIENTO ESTA CARACTERIZADO POR EL EMPLEO DE SISTEMAS CATALITICOS COMPUESTOS DE UN SOLO CATALIZADOR METALOCENO ACTIVADO CON MEZCLAS DE AL MENOS DOS COCATALIZADORES. LOS COCATALIZADORES SON ALQUILOS DE ALUMINIO, ALUMINOXANOS O COMPUESTOS DE BORO. MEDIANTE EL EMPLEO DE ESTOS SISTEMAS COCATALITICOS MIXTOS SE PRODUCEN DIFERENTES CENTROS ACTIVOS EN EL CATALIZADOR, CADA UNO CON DIFERENTES VELOCIDADES DE INICIACION Y TERMINACION DE LA REACCION DE POLIMERIZACION, LOS CUALES PRODUCEN POLIOLEFINAS CON DIFERENTES PESOS MOLECULARES, DANDO COMO RESULTADO PRODUCTOS CON DISTRIBUCIONES DE PESO MOLECULARES ANCHAS, BIMODALES O MULTIMODALES. LAS DISTRIBUCIONES DE PESO MOLECULARES, Y LA INCORPORACION DE COMONOMERO, SE PUEDE CONTROLAR MEDIANTE LA SELECCION ADECUADA DEL METALOCENO Y EL EMPLEO DE LAS COMBINACIONALES DE LOS DIFERENTES TIPOS DE COCATALIZADORES, ASI COMO VARIANDO LA PRESION DEL REACTOR, LA TEMPERATURA DE LA REACCION Y LAS RELACIONES MOLARES ENTRE LOS DIFERENTES COMPONENTES DEL SISTEMA CATALITICO. LA DISTRIBUCION DE PESOS MOLECULARES ANCHA, BIMODAL O MULTIMODAL SE PUEDE CONSEGUIR TANTO EN AUSENCIA COMO EN PRESENCIA DE HIDROGENO DURANTE LA REACCION DE POLIMERIZACION. DE IGUAL FORMA SE PUEDEN CONSEGUIR DISTRIBUCIONES DE PESOS MOLECULARES ANCHAS, BIMODALES Y MULTIMODALES EN LOS POLIMEROS VARIANDO EL ORDEN DE ADICION DE LOS COMPONENTES DEL SISTEMA CATALITICO. ESTE PROCEDIMIENTO SE PUEDE EMPLEAR TANTO EN EL CASO DE CATALIZADORES METALOCENO HOMOGENEOS COMO HETEROGENEOS. FIG. 1.
