Abstract
SE PREPARA UN CATALIZADOR DE COPOLIMERIZACION DE UNA ETILEN ALFA - OLEFINA MEDIANTE LA IMPREGNACION DE UN SOPORTE POROSO, COMO SILICE, CON UNA MEZCLA DE CONTACTO DE UN COMPUESTO DE ORGANOMAGNESIO, COMO DIALQUIL MAGNESIO, Y UN COMPUESTO DE SILANO EXENTO DE GRUPOS HIDROXILO, COMO TETRAETIL ORTOSILICATO. A CONTINUACION SE INCORPORA UN COMPONENTE DE UN METAL DE TRANSICION, COMO TETRACLORURO DE TITANIO, EN EL INTERIOR DEL SOPORTE, EN UNA RELACION ESPECIFICA RESPECTO A LOS COMPONENTES DE SILANO Y MAGNESIO. LA ACTIVACION DE DICHO PRECURSOR CATALITICO CON UN COMPUESTO DE TRIALQUILALUMINIO PRODUCE UN SISTEMA CATALIZADOR EFECTIVO PARA LA PRODUCCION DE COPOLIMEROS DE ETILENO.
