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