Abstract

LA INVENCION SE ORIENTA EN GENERAL A UN SISTEMA CATALIZADOR SOPORTADO UTIL PARA LA POLIMERIZACION DE OLEFINAS. EL METODO PARA LA FORMACION DEL SISTEMA CATALIZADOR DE LA INVENCION PROPORCIONA UN SOPORTE PARA UN COMPUESTO METALICO DE TRANSICION DE UN LIGANDO VOLUMINOSO EN UN SOPORTE Y APOYA POR SEPARADO UN COCATALIZADOR O ACTIVADOR PARA EL COMPUESTO VOLUMINOSO. EL COMPUESTO METALICO DE TRANSICION DE LIGANDO VOLUMINOSO DE LA INVENCION PUEDE SER UN METALOCENO. LOS SISTEMAS CATALIZADORES METALOCENICOS DE LA INVENCION TIENEN UNA ELEVADA ACTIVIDAD FUERA DE LO COMUN EN COMPARACION CON LOS SISTEMAS CATALIZADORES PREVIAMENTE DESCRITOS EN LOS QUE EL METALOCENO Y EL ACTIVADOR ESTAN EN UN PORTADOR. LA INVENCION PROPORCIONA LA POSIBILIDAD DE MANIPULAR EL SISTEMA CATALIZADOR FACILMENTE VARIANDO LAS CANTIDADES DE LOS COMPONENTES SOPORTADOS INDIVIDUALMENTE. HASTA AHORA LOS SISTEMAS CATALIZADORES PREVIOS HABIAN TENIDO QUE REFORMULARSE DE FORMA IMPROVISADA, LO QUE ERA CARO Y LLEVABA TIEMPO. ADEMAS AHORA ES POSIBLE, MEDIANTE LOS SISTEMAS CATALIZADORES DE LA INVENCION CAMBIAR CONVENIENTEMENTE EL SISTEMA CATALIZADOR, AJUSTANDO EL CATALIZADOR AL PORCENTAJE DEL ACTIVADOR EN UN PROCESO DE POLIMERIZACION CONTINUO, EN CONCRETO EN UN PROCESO DE FASE GASEOSA Y PARA PERMITIR PERIODOS DE TRANSICION MAS RAPIDOS ENTRE DISTINTAS CLASES DE LOS POLIMEROS.
