Abstract

UN PROCEDIMIENTO DE PREPARACION DE UN CATALIZADOR QUE CONTIENE CROMO, PARA LA POLIMERIZACION DE OLEFINAS.SE DEPOSITA SOBRE UN SOPORTE INERTE, ADEMAS DEL COMPLEJO DE CROMO, UN COMPUESTO DE VANADIO CON UNO O MAS COMPUESTOS ORGANOMETALICOS DE UN METAL DE LOS GRUPOS II O III, NO SIENDO EL COMPUESTO DE PARTIDA, UN COMPUESTO 1,3-DICETO SI SE USA UN COMPLEJO DE VANADIO. DICHO COMPUESTO DE VANADIO SE HACE REACCIONAR CON 0,5 O 20 MOLES DE COMPUESTOS ORGANOMETALICO POR MOL DE VANADIO. LA RELACION MOLAR DEL CROMO AL VANADIO ES DE 1:50 A 50:1.
