The present invention is directed to a method for preparing polyolefins containing a high percentage of exo-olefin chain ends. The method involves ionizing a polyolefin containing tert-chloride chain ends and reacting the ionized polyolefin with one or more nitrogen-containing five-membered aromatic ring or one or more hindered secondary or tertiary amines, or mixtures thereof.
La présente invention porte sur un procédé de préparation de polyoléfines contenant un pourcentage élevé de groupes terminaux d'exo-oléfines. Le procédé consiste à ioniser une polyoléfine contenant des groupes terminaux de chlorure de tert et à faire réagir la polyoléfine ionisée avec un ou plusieurs noyaux aromatiques à cinq éléments contenant de l'azote ou un ou plusieurs amines secondaires ou tertiaires inhibés, ou des mélanges de ceux-ci.
