Abstract
SE DESCRIBE UNA POLIMERIZACION DE OLEFINAS QUE UTILIZA UN CATALIZADOR BASADO EN COMPLEJOS PI-ARENO DE METALES LANTANIDOS EN PARTICULAR EL CATALIZADOR SE SOPORTA EN SUPERFICIES HIDROXILICAS O HIDROFILICAS CONCRETAMENTE SUPERFICIES DE HALIDO SILICE O ALUMINA,Y MAS CONCRETAMENTE CLORURO DE MAGNESIO. EL CATALIZADOR POLIMERIZA EL ETILENO Y TAMBIEN EL PROPILENO PARA DAR UN POLIMERO MUY ISOTACTICO SIN UTILIZAR UN DONANTE DE ELECTRODO QUE INTENSIFIQUE LA REGULARIDAD ESTEREO.TAMPOCO SE REQUIEREN CO-CATALIZADORES PARA ACTIVAR LA POLIMERIZACION.
