Abstract

Descrito aquí está un proceso y un aparato para la preparacion de homopolímeros y copolímeros de propileno que comprende la polimerizacion opcional depropileno con comonomeros en presencia de un catalizador a temperatura y presion elevadas en almeno s un reactor de suspension y al menos un reactor de fasegaseosa, el producto de polimerizacion de al menos un reactor de suspension conteniendo monomeros sin reaccionar, siendo conducidos a un primer reactor de fasegaseosa esencialmente sinreciclaje de los monomeros sin reaccionar al reactor de suspension. La invencion proporciona rápidos arranques porque el material dellecho de la fase gaseosa está directamente disponible del reactor de curvatura.
