Abstract

SE HOMOPOLIMERIZA ETILENO, EN PRESENCIA DE UN CATALIZADOR CONSISTENTE ESENCIALMENTE EN UN COMPLEJO DE UN METAL DEL GRUPO 3, PREFERIBLEMENTE UN COMPLEJO DE ESCANDIO, QUE PRESENTA UNA ESTRUCTURA DE LIGANDO PUENTEADA. OPCIONALMENTE, SE PUEDEN PREPARAR MEZCLAS POLIMERICAS, COMBINANDO EL PROCEDIMIENTO ANTERIOR, CON OTRO PROCEDIMIENTO DE POLIMERIZACION, BIEN EN SERIE O EN PARALELO.
