Abstract

SE DESCRIBE LA PREPARACION DE UN SISTEMA CATALITICO TIPO ZIEGLER POR LA IMPREGNACION DE UNA ALUMINA ESPECIAL CON 0,8-1,0% P/P DE TITANIO A PARTIR DE UNA SOLUCION DILUIDA DE HALURO DE TITANIO EN N-HEXANO, EMPLEANDOSE EL ACTIVADOR TRISOBUTILALUMINIO O TRIETILALUMINIO, ESTANDO LA RELACION MOLAR [AL]/[TI] EN EL CATALIZADOR ENTRE 2,5/1 Y 80/1. EL SISTEMA CATALITICO PRESENTA ELEVADA DEFICIENCIA Y PRODUCTIVIDAD, CONDUCIENDO A POLIETILENOS DE EXCELENTES PROPIEDADES FISICAS Y MECANICAS, QUE LO HACEN ESPECIALMENTE ADECUADO PARA USO COMO PLASTICO DE INGENIERIA.
