Abstract

Il est décrit un procédé de polymérisation en solution continue à trois réacteurs. Du solvant de traitement, de léthylène, des comonomères facultatifs, de lhydrogène facultatif et un système catalyseur à site unique sont injectés dans un premier réacteur et un deuxième réacteur configurés en parallèle lun par rapport à lautre. Un troisième réacteur reçoit un effluent provenant du premier réacteur, du deuxième réacteur ou dune combinaison des premier et deuxième réacteurs. Un monomère frais est introduit dans le troisième réacteur pour une polymérisation supplémentaire et pour donner un produit final en polyéthylène.
