Abstract

METODO PARA LA PREPARACION DE CATALIZADORES A BASE DE CROMO SOBRE ALUMINA PARA POLIMERIZACION DE OLEFINAS. COMPRENDE LAS SIGUIENTES OPERACIONES: PRIMERA, SE TRATA UN GEL DE ALUMINA O UN GEL DE FOSFATO DE ALUMINIO DE BAJO CONTENIDO EN FOSFORO CON UN AGENTE DE FOSFATACION; SEGUNDA, SE ACTIVA EL GEL ASI TRATADO EN UNA ATMOSFERA OXIDANTE Y A UNA TEMPERATURA ELEVADA, TENIENDO DICHO GEL UN COMPUESTO DE CROMO COPRECIPITADO CON EL O UN COMPUESTO DE CROMO AÑADIDO A EL ANTES DE DICHA ACTIVACION; Y POR ULTIMO, DE MANERA OPCIONAL, SE PUEDE COMBINAR UN COCATALIZADOR ORGANOMETALICO CON EL CATALIZADOR ASI ACTIVADO. EL AGENTE DE FOSFATACION UTILIZADO ES ACIDO FOSFORICO Y EL COCATALIZADOR ES TRI-N-BUTILBORANO.
