Abstract

METODO DE PREPARACION DE COPOLIMEROS DE BLOQUES DE ETILENO-PROPILENO. COMPRENDE UNA PRIMERA OPERACION DE POLIMERIZACION PARA LA FORMACION DE UN PREPOLIMERO DE PROPILENO, QUE CONTIENE, AL MENOS, 98% DE GRUPOS PROPILENO; SEGUIDA DE UNA POLIMERIZACION DE ETILENO Y PROPILENO PARA FORMAR UN COPOLIMERO DE BLOQUES DE ETILENO-PROPILENO CON UNA PARTE DE PROPILENO CASI COMPLETAMENTE HOMOPOLIMERA Y OTRA COPOLIMERA, EN UNA RELACION EN PESO COMPRENDIDA ENTRE 3:2 Y 4:1, RESPECTIVAMENTE; Y SOMETER EL COPOLIMERO DE BLOQUES A UN TRATAMIENTO DE AMASADO, EN PRESENCIA DE RADICALES LIBRES, A UNA TEMPERATURA NO INFERIOR A 450C. ESTOS COPOLIMEROS TIENEN APLICACIONES EN AMORTIGUADORES DE COCHES, EXTREMOS FRONTALES, ALERONES, FORROS Y REVESTIMIENTOS INFERIOR Y DE ARCOS DE RUEDAS PARA VEHICULOS A MOTOR.
