    摘要: 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.

    摘要: Conjugated diolefins, optionally in combination with other unsaturated compounds which may be copolymerized with the diolefins, are polymerized by performing the polymerization of the diolefins in the presence of catalysts based on cobalt compounds, organoaluminum compounds and modifiers in the presence of aromatic vinyl compounds at temperatures of −30° C. to +80° C. By means of the process according to the invention, it is possible straightforwardly to produce solutions of polydiolefins, such as polybutadiene, having different 1,2 unit contents in aromatic vinyl compounds, which solutions may then, for example, be further processed to yield ABS or HIPS.
