Abstract

COPOLIMERIZADOS DE PROPILENO CON 1-ALQUENOS, PUEDEN OBTENERSE POR POLIMERIZACION EN DOS ETAPAS, EN FASE GASEOSA Y EN UN LECHO MOVIL, MEDIANTE UN SISTEMA DE CATALIZADORES ZIEGLER-NATTA, QUE JUNTO A UN COMPONENTE SOLIDO QUE CONTIENE TITANIO, CONTIENE ADEMAS UN COMPUESTO DE ALUMINIO, DE MODO QUE A) EN LA PRIMERA ETAPA DE POLIMERIZACION A UNA PRESION DE 15 A 40 BARES, 50-90 C DE TEMPERATURA Y UN TIEMPO MEDIO DE PERMANENCIA DE LA MEZCLA REACTIVA DE 1 A 5 HORAS, SE POLIMERIZA EL PROPILENO JUNTO CON OTRO 1-ALQUENO DANDO, POR MMOL DE COMPUESTO DE ALUMINIO, 0,05-2 KG DE COPOLIMERIZADO DE PROPILENO, SIENDO LA PROPORCION ENTRE PRESION PARCIAL DEL PROPILENO Y EL DEL OTRO 1-ALQUENO DE 5:1 HASTA 500:1, Y A CONTINUACION B) EN UNA SEGUNDA ETAPA DE POLIMERIZACION A UNA PRESION DE 5-30 BARES, SIENDO ESTA PRESION 7 BARES INFERIOR, COMO MINIMO, A LA PRESION DE LA PRIMERA ETAPA DE POLIMERIZACION, UNA TEMPERATURA DE 30 A 100 C Y UN TIEMPO MEDIO DE PERMANENCIA DE LA MEZCLA REACTIVA DE 1-5 HORAS, AL POLIMERIZADO QUE SALE DE LA PRIMERA ETAPA SE LE COPOLIMERIZA CON PROPILENO Y OTRO 1-ALQUENO MAS, AJUSTANDO LA RELACION ENTRE PRESIONES PARCIALES DE PROPILENO Y EL OTRO 1-ALQUENO EN 0,5:1 20:1 Y MIDIENDO LA PROPORCION EN PESO DE LOS MONOMEROS QUE REACCIONAN EN LA PRIMERA Y SEGUNDA ETAPA DE POLIMERIZACION DE TAL MODO QUE ESTE ENTRE 0,5:1 Y 20:1. LOS COPOLIMERIZADOS SIRVEN SOBRE TODO PARA LA PRODUCCION DE LAMINAS Y DE CUERPOS MOLDEADOS.
