Abstract
SE DESCRIBE UN PROCESO PARA LA PREPARACION DE COPOLIMEROS DE ETILENO-BUTENO-1 QUE TIENEN DENSIDADES CON VALORES DE ALREDEDOR DE 0,880 A ALREDEDOR DE 0,914 G/ML, PARA LA COPOLIMERIZACION DE ETILENO Y BUTENO-1, A ALTA PRESION Y A ALTA TEMPERATURA, EN UNA VASIJA DE REACTOR O EN UN REACTOR TUBULAR, EN PRESENCIA DE UN CATALIZADOR QUE CONTIENE TRIALQUILO DE ALUMINIO Y UN COMPONENTE CATALIZADOR SOLIDO QUE CONTIENE DE 0,4 A 4,0 % DE PESO DE TITANIO SOBRE UN SOPORTE DE CLORURO MAGNESICO MICROESFERICO, EN EL CUAL EL TITANIO ESTA PARCIALMENTE PRESENTE EN FORMA TETRAVALENTE Y PARCIALMENTE EN LA TRIVALENTE. LOS COPOLIMEROS ASI OBTENIDOS SE USAN PARA LA PRODUCCION DE PELICULA, PRODUCTOS ESTAMPADOS Y MEZCLADO CON OTROS POLIMEROS.
