Abstract

UN PROCEDIMIENTO DE PREPARACION DE UN SOPORTE CATALITICO, BASADO EN UNA ALUMINA ESPECIAL MODIFICADA CON CANTIDADES VARIABLES DE CLORURO DE MAGNESIO, CONDUCIENDO UNA PROPORCION MAYOR DE MGCL2 A UNA CANTIDAD MENOR DE CADENAS MOLECULARES PESADAS EN EL POLIMERO FINAL. EL SOPORTE, PREPARADO MEDIANTE LA MOLIENDA DE LA ALUMINA ESPECIAL JUNTO CON EL MGCL2 PREVIAMENTE TRATADO CON ETILOBENZOATO, ES IMPREGNADO CON TICL4 CON EL FIN DE CREAR EL CATALIZADOR. LOS CATALIZADORES RESULTANTES MUESTRAN UNA ELEVADA ACTIVIDAD, LO QUE PERMITE QUE SE EVITE EL RESIDUO METALICO Y LA FASE DE ELIMINACION DEL CLIRURO EN LA RESINA ASI CREADA. ADICIONALMENTE, LOS TIPOS DE DISTRIBUCION DEL PESO MOLECULAR Y DE LAS PROPIEDADES MECANICAS SON DISTINTOS PARA LOS POLIMEROS PRODUCIDOS.
