Abstract:
The invention relates to new catalysts based on compounds of the rare earth metals containing a compound of the rare earth metals, a cyclopentadiene, and an alumoxane, as well as the use of new catalysts for the polymerisation of unsaturated compounds, particularly conjugated dienes. With the new catalyst system it is possible in the polymerisation of conjugated dienes to obtain a substantially higher proportion of laterally bound vinyl groups in the polymers.
