Abstract

L'invention décrit un procédé perfectionné de production de polyéthylène. On polymérise de l'éthylène seul ou avec des comonomères et/ou des télogènes ou modificateurs dans un réacteur tubulaire allongé, ayant une entrée et une sortie et contenant de préférence quatre zones de réaction et quatre zones de refroidissement On peut obtenir plus de 28 % (et jusqu'à 40 %) de transformation de l'éthylène, sans perte des caractéristiques optiques ou physiques du polymère obtenu (voir figure unique).The invention describes an improved process for producing polyethylene. Ethylene is polymerized alone or with comonomers and / or telogens or modifiers in an elongated tubular reactor, having one inlet and one outlet and preferably containing four reaction zones and four cooling zones. More than 28% can be obtained. (and up to 40%) transformation of ethylene, without loss of the optical or physical characteristics of the polymer obtained (see single figure).
