Abstract
La presente se relaciona con un proceso de polimerizacion de isobuteno en donde se mantiene constante una propiedad P (viscosidad o peso molecular medio)del poliisobuteno producido. La polimerizacion se efectua de modo continuo en un reactor quecomp rende una fase de reaccion líquida en ebullicion en equilibriocon una fase gaseosa, mediante la introduccion continua en el reactor de un catalizador y de una mezcla de alimentacion hidrocarbonada C4 que comprende elmonomero, y medianteextraccion co ntinua del reactor de la fase de reaccion líquida. El proceso comprende la determinacion de un valor diana V de la presionparcial, PiC4, del isobuteno en la fase gaseosa del reactor correspondiente al valor deseado de la propiedad P,en virtud de una relacion empírica establecidade antemano entre la propiedad P del poliisobuteno producido y PiC4. Durante la polimerizacion, se mide la PiC4 y se calcula un valor corregido de PiC4,(PiC4)c, el cual se mantiene constante alrededordel valor diana V, actuando sobre la velocidad de flujo Qc del catalizador y/o sobre la velocidad de flujo Qhde la mezcla de alimentacion hidrocarbonada C4.
