Abstract
PROCEDIMIENTO PARA LA COPOLIMERIZACION DE ISOOLEFINAS, ESPECIALMENTE DE ISOBUTENO, CON DIMETIBUTADIENO, EN SOLUCION O EN MASA. SE POLIMERIZA LA OLEFINA EN UN DISOLVENTE INERTE, AUNQUE TAMBIEN SE PUEDE EFECTUAR EN MASA SIRVIENDO EL MONOMERO SIN REACCIONAR COMO DISOLVENTE, Y EN PRESENCIA DE UN SISTEMA CATALIZADOR QUE ES UN PRODUCTO DE REACCION DE UN COMPUESTO DE ALUMINIO ORGANICO SELECCIONADO DE COMPUESTOS DE FORMULAR (I), (II) Y (III) DONDE R SIGNIFICA RESTOS DE HIDROCARBURO (CICLO) ALIFATICOS SATURADOS CON 1 HASTA 10 ATOMOS DE CARBONO, Y X SIGNIFICA UN ATOMO DE HALOGENO, EL SISTEMA CATALIZADOR TAMBIEN DEBE CONTENER UN COMPUESTO DE FORMULA (IV) DONDE X ES UN ATOMO DE HALOGENO TAL COMO CLORO, BROMO O IODO. LA POLIMERIZACION SE PUEDE REALIZAR DE FORMA CONTINUA O DISCONTINUA Y UNA VEZ FINALIZADA SE DESAVTIVA EL CATALIZADOR MEDIANTE ADICION DE ALCOHOLES, AMINAS O ACIDOS CARBOXILICOS. EL POLIMERO SE PUEDE AISLAR MEDIANTE STRIPPING, PRECIPITACION O EVAPORIZACION.
