Abstract

SE PRESENTA UN PROCESO DE POLIMERIZACION EN DOS PASOS PARA PRODUCIR UNA POLIOLEFINA QUE TIENE UNA DISTRIBUCION BIMODAL DE PESO MOLECULAR. EN EL PASO UNO, BAJO CONDICIONES DE POLIMERIZACION, SE PONEN EN CONTACTO AL MENOS DOS ALFA-OLEFINAS DIFERENTES CON UN SISTEMA CATALIZADOR QUE COMPRENDE UN ALUMINOXANO Y UN METALOCENO, SELECCIONADOS ENTRE EL GRUPO QUE CONSTA DE MONO, DI Y TRI-CICLOPENTADIENILES Y CICLOPENTADIENILES SUBSTITUIDOS, DE UN METAL SELECCIONADO ENTRE TITANIO, VANADIO, CROMO, CIRCONIO, NIOBIO, MOLIBDENO, HAFNIO, TANTALIO Y TUNGSTENO, CON LA CONDICION DE QUE SI DICHO METAL ES TITANIO ENTONCES ESTARA PRESENTE UN METALOCENO DE AL MENOS ALGUN OTRO DE DICHOS METALES DE MANERA QUE SE FORME UNA PRIMERA MEZCLA DE POLIMERIZACION QUE COMPRENDA UN COPOLIMERO DE BAJA CRISTALINIDAD Y ALTO PESO MOLECULAR, UN MONOMERO NO REACCIONADO, UN COMONOMERO NO REACCIONADO Y EL CATALIZADOR. TODO ELLO VA SEGUIDO POR LA PUESTA EN CONTACTO, BAJO CONDICIONES DE POLIMERIZACION, DE HIDROGENO (Y OPCIONALMENTE ALFA-OLEFINA ADICIONAL), CON DICHA PRIMERA MEZCLA DE POLIMERIZACION QUE COMPRENDE COPOLIMERO, MONOMERO NO REACCIONADO, COMONOMERO NO REACCIONADO Y EL CATALIZADOR DE MANERA QUE SE FORME UNA SEGUNDA MEZCLA DE POLIMERIZACION QUE COMPRENDA UN COPOLIMERO DE BAJA CRISTALINIDAD Y ALTO PESO MOLECULAR, Y UN HOMOPOLIMERO DE ALTA CRISTALINIDAD Y BAJO PESO MOLECULAR.
