Abstract
PREPARACION DE UN CATALIZADOR A BASE DE TITANIO, HAFNIO Y ZIRCONIO. EL CATALIZADOR SE OBTIENE POR EVAPORACION EN VACIO DE MG Y REACCION DE LOS VAPORES OBTENIDOS CON UN COMPUESTO DE TITANIO TETRAVALENTE, EN PRESENCIA DE UN DONADOR DE ATOMOS DE HALOGENO Y DE UN COMPUESTO DE ZR O HF; A LA MEZCLA OBTENIDA SE LE AÑADE UN ALCOHOL R-OH, DONDE R ES UNA CADENA ALIFATICA, LINEAL O RAMIFICADA, DE 1 A 10 C Y SE SOMETE A CALEFACCION ENTRE 50 Y 100JC; A LA MEZCLA ASI OBTENIDA SE LE AÑADE AL MENOS UN COMPUESTO ORGANOMETALICO DE ALUMINIO; ALRK3-YXY, DONDE RK ES UN RADICAL DE HIDROCARBURO, X UN HALOGENO E Y UN NUMERO ENTRE 0 Y 2 Y LA MEZCLA SE CALIENTA DE NUEVO A 80-100JC. EL COMPUESTO DE ZR O HF PUEDE SER TETRACLORURO DE ZR O HF O TETRAALCOHOLATOS DE ZR. EL COMPUESTO DE TI PUEDE SER UN DERIVADO HALOGENADO O ALQUIL- O ARILTITANIOS. EL CATALIZADOR SE EMPLEA EN PROCESOS DE HOMOPOLIMERIZACION DE ETILENO Y DE COPOLIMERIZACION DE ETILENO CON ALFA-OLEFINAS, OBTENIENDOSE POLIMEROS CON UNA AMPLIA DISTRIBUCION DE PESOS MOLECULARES.
