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).
