Abstract
SE PRESENTAN CATALIZADORES MIXTOS DE CROMO PERFECCIONADOS UTILES EN POLIMERIZACIONES EN FORMA DE PARTICULAS PARA PRODUCIR RESINAS DE POLIOLEFINAS DE ALTA DENSIDAD FACILMENTE PROCESABLES QUE TAMBIEN TIENEN ALTA RESISTENCIA AL AGRIETAMIENTO POR TENSION AMBIENTAL. PARA LA PREPARACION DE LOS CATALIZADORES MIXTOS SE EMPLEAN UN PRIMER Y UN SEGUNDO COMPONENTES CATALIZADORES OBTENIDOS USANDO SOPORTES DE SILICE DE DISTINTOS VOLUMENES DE PORO Y DONDE UNO DE ELLOS CONTIENE TAMBIEN ALUMINIO. TAMBIEN SE DESCRIBE EL PROCEDIMIENTO DE POLIMERIZACION Y PRODUCTOS OBTENIDOS USANDO LOS CATALIZADORES MIXTOS ANTES DESCRITOS.
