Abstract
SE PRESENTA UN CATALIZADOR SOPORTADO "ZIEGLER-NATTA" ACTIVO EN LA POLIMERIZACION DEL ETILENO Y EN LA COPOLIMERIZACION DEL ETILENO CON OLEFINAS ALFA QUE CONSTA DE: A) UN COCATALIZADOR EN LA FORMA DE UN COMPUESTO ORGANOMETALICO DE ALUMINIO , Y B) UN COMPONENTE CATALIZADOR SOLIDO OBTENIDO MEDIANTE: I) LA IMPREGNACION DE UN SOPORTE SOLIDO GRANULAR CON UNA SOLUCION DE ALCOHOLATO DE TITANIO Y CLORURO DE MAGNESIO EN UN HIDROCARBORO HALIFATICO LIQUIDO, SEGUIDA DE LA EVAPORACION DEL SOLVENTE HIDROCARBONO; II) LA IMPREGNACION DEL SOPORTE TRATADO EN I) CON UNA SOLUCION DE CLORURO DE MAGNESIO EN UN ESTER HALIFATICO LIQUIDO SEGUIDA DE LA EVAPORACION DEL SOLVENTE ESTER; III) LA ACTIVACION DEL SOPORTE TRATADO EN II) MEDIANTE SU PUESTA EN CONTACTO CON UN ALURO DE ALUMINIO DE ALQUIL. EN UNA CONFORMACION MAS ADECUADA SE INTRODUCEN CANTIDADES CONTRASTADAS DE ALURO DE SILICIO EN LA ETAPA I) Y/O II), ESTO MEJORA CONSIDERABLEMENTE LA ACTIVIDAD CATALITICA. EN UNA CONFORMACION PARTICULAR, SE INTRODUCEN ZIRCONIO OHAFNIUM EN EL COMPONENTE CATALIZADOR SOLIDO B) EN ADICION AL TITANIO, PARA OBTENER CATALIZADORES CAPACES DE PRODUCIR POLIETILENOS CON UNA DISTRIBUCION DE PESO MOLECULAR AMPLIADA.
