CA 2294943

Transition metal complexes suitable for use for the polymerisation of olefins comprise unsaturated groups having Lewis Base functionality. Preferred groups are dienes having dialkylamino functionality. The complexes may suitably be supported by the use of the functionalised dienes to give transition metal complexes which in the presence of activators are particularly suitable for gas phase processes.

L'invention concerne des complexes de métaux de transition indiqués pour la polymérisation d'oléfines et comprenant des groupes insaturés possédant une fonctionnalité de base de Lewis. Les groupes préférés sont des diènes possédant une fonctionnalité dialkylamine. Les complexes peuvent être supportés de manière appropriée par utilisation des diènes fonctionnalisés pour produire des complexes de métaux de transition qui, en présence d'activateurs, sont particulièrement indiqués dans des procédés en phase gazeuse.
