Abstract

LA INVENCION SE REFIERE A UN PROCESO PARA LA PREPARACION DE UN POLIPROPILENO PARA, POR EJEMPLO, APLICACIONES EN TUBERIAS, QUE CONTIENE DE 1,0 A 10,0 % EN PESO DE ETILENO O UNIDADES REPETITIVAS DE C4-C10 - AL - OLEFINA Y QUE TIENEN UN VALOR MFR 2 ENTRE 0,05 Y 0,04 G/10 MIN, POLIMERIZA NDO PROPILENO Y ETILENO EN PRESENCIA DE UN SISTEMA DE CATALISIS. LA RESISTENCIA AL RESQUEBRAJAMIENTO DEL POLIPROPILENO SE MEJORA REALIZANDO EL PROCESO POR MEDIO DE LOS SIGUIENTES PASOS: (A) COPOLIMERIZANDO EL PROPILENO Y EL ETILENO EN UN COPOLIMERO AL AZAR A UNOS 40 A 110º C UTILIZANDO: UNA PORCION DE ETILENO DE C4-C10 - AL OLEFINA LLEVANDOLO A UN 1,0 A 10,0% EN PESO DE UNIDADES REPETITIVAS DE ETILENO EN DICHO COPOLIMERO AL AZAR, Y SIN NINGUNA O CON UNA MINIMA CANTIDAD DE HIDROGENO QUE SE LLEVA A UN VALOR MFR 10 DE ENTRE 0,01 Y 5,0 G/10 MIN PARA DICHO COPOLIMERO AL AZAR, SI ESTE PASO SE REALIZA PRIMERO, O A UN VALOR MFR2 PARA DICHO POLIPROPILENO DE ENTRE 0,05 A 0,40 G/10 MIN, SI ESTE PASO SE REALIZA DESPUES DELPASO (B); SIENDO LA PROPORCION DEL COPOLIMERO AL AZAR DE ESTE PASO DE 20 A 80% EN PESO DE DICHO POLIPROPILENO, (B) POLIMERIZANDO EL PROPILENO CON UNOS 40 A 110º C UTILIZANDO; NINGUNA O UNA MINIMA PORCION DE ETILENO QUE SE LLEVA DE 0,0 A 1,0% EN PESO DE UNIDADES REPETITIVAS DE ETILENO EN EL POLIMERO RESULTANTE DE ESTE PASO; Y UNA CANTIDAD DE HIDROGENO LLEGANDO A UN VALOR MFR2 DE DICHO POLIPROPILENO DE ENTRE 0,05 Y 0,40 G/10 MIN, SI ESTE PASO SE REALIZA DESPUES DEL PASO (A); SIENDO LA PROPORCION DE POLIMERO DE ESTE PASO DE 80 A 20% EN PESO DE DICHO POLIPROPILENO. EL POLIPROPILENO PUEDE SER MODIFICADO POR ELASTOMEROS.
