Abstract

LA PRESENTE INVENCION SE REFIERE A UN PROCESO PARA LA PRODUCCION DE POLIMEROS Y COPOLIMEROS DE OLEFINAS CH2=CHR, EN DONDE R ES UN ATOMO DE HIDROGENO O UN RADICAL ALQUILO O ARILO QUE TIENE UN NUMERO DE ATOMOS DE CARBONO ENTRE 1 Y 10 Y QUE CONSISTE EN UN PASO DE (CO)POLIMERIZACION EN LA FASE DE GAS POR LO MENOS, EN PRESENCIA DE UN CATALIZADOR MUY ACTIVO OBTENIDO DE UN COMPUESTO DE TITANIO SOPORTADO EN UN HALURO DE MAGNESIO EN FORMA ACTIVA Y UN COMPUESTO AL-ALQUILO. EL PROCESO SE CARACTERIZA POR EL HECHO DE QUE SE REALIZA A BASE DE ALIMENTAR UNA CANTIDAD PEQUEÑA EN COMPARACION AL POLIMERO DE UN COMPUESTO QUE TIENE POR LO MENOS DOS GRUPOS, IGUALES O DIFERENTES, CAPACES DE REACCIONAR CON EL COMPUESTO DE ALUMINIO DE ALQUILO Y CAPACES DE INHIBIR DE FORMA SELECTIVA LA REACTIVIDAD DE PEQUEÑAS PARTICULAS DE POLIMEROS SI SE COMPARA CON EL TAMAÑO GRANULOMETRICO MEDIO DEL POLIMERO PRESENTE EN LA FASE DE GAS.
