Abstract

PROCEDIMIENTO MEJORADO DE POLIMERIZACION DE ALFA-OLEFINAS EN UN REACTOR DE LECHO FLUIDIZADO CON CATALIZADORES A BASE DE TITANIO U OTROS QUE DAN LUGAR A FORMACION DE LAMINAS DURANTE LA POLIMERIZACION. LA MEJORA CONSISTE EN MANTENER LA CARGA ESTATICA EN DICHO REACTOR, EN EL PUNTO POSIBLE DE FORMACION DE LAMINAS, POR DEBAJO DE LOS NIVELES DE VOLTAJE QUE PODRIAN DAR LUGAR A LA FORMACION DE HOJAS, MEDIANTE LA INTRODUCCION EN EL REACTOR DE UN COMPUESTO DE CROMO EN ESTADO DE VALENCIA 2 O 3, EN UN DISOLVENTE INERTE COMO EL TOLUENO. APLICABLE A LA HOMO Y COPOLIMERIZACION DE ETILENO, PROPILENO, BUTENO-1, PENTENO-1, HEXENO-1, 4-METILPENTENO-1, HEPTENO-1 U OCTENO-1.
