Abstract

UN METODO DE POLIMERIZACION EN DOS ETAPAS BAJO LA UTILIZACION DE UN CATALIZADOR SOPORTE MODIFICADO POLIMEROS DE ETILENO CON MUY BUENAS PROPIEDADES DE ELABORACION Y EXCELENTES PRODUCCIONES DE PIEZAS ACABADAS. LA UTILIZACION DEL CATALIZADOR SOPORTE SE PRODUCE POR LA TRANSFORMACION DE UN ALCOLATO DE MAGNESIO CON UN COMPUESTO DE TITANIO - IV EN SUSPENSION Y LA INMEDIATA REACCION CON UN COMPUESTO DE ALUMINIO ORGANICO, QUE CONTIENE HALOGENO, Y LA ACTIVACION DE LOS MATERIALES SOLIDOS ASI OBTENIDOS POR UN TRIALQUILO DE ALUMINIO O UN ISOPRENILO DE ALUMINIO.
