This invention relates to a vertically disposed polymerization reactor (2) having a series of essentially circular tray assem- blies (10); each tray assembly (10) having a central open vapor chimny (18) and a single flow path (26) composed of at least two loops (30, 32) wherein the liquid poly- mer flow is reversed by means of a substan- tially semi-circular turnaround wall (24); said trays havig a liquid polymer tray inlet (14) and a liquid polymer tray oudet (16) for conducting a flow of the liquid polymer by means of a hydraulic gradient; each tray assembly (10) being open at the top for es- cape of vapor from thG liquid polymer flow to the central open vapor chimny (18),and said trays (10) arranged vertical disposi- tion one above the other.

Réacteur (2) de polymérisation placé verticalement qui possède une série d'ensembles plateaux (10) essentiellement circulaires. Chaque ensemble plateau (10) est pourvu d'une cheminée (18) à vapeur centrale ouverte et d'un seul passage de flux (26) composé d'au moins deux boucles (30, 32), le flux de polymère liquide étant inversé à l'aide d'une région (24) de changement de sens pratiquement semi-circulaire. Lesdits plateaux (10) possèdent un orifice d'entrée (14) de polymère liquide et un orifice de sortie (16) de polymère liquide permettant d'acheminer un flux de polymère liquide à l'aide d'un gradient hydraulique. Chaque ensemble plateau est ouvert dans sa partie supérieure pour que la vapeur puisse s'échapper du flux de polymère liquide vers la cheminée (18) à vapeur centrale ouverte. Lesdits plateaux (10) sont disposés verticalement les uns au-dessus des autres.
