    摘要： The block copolymers according to the invention which are based on conjugated diolefins and polar monomers and are prepared in the presence of catalysts based on the rare earth metals have a high cis-1,4 content in the polydiene block and, because of their polar polymer part and their non-polar diene polymer part, can be used as agents which impart compatibility in the preparation of vulcanizates with a filler content for the production of tires and tire component in the preparation of thermoplastic elastomers or in the modification of thermoplastics.

    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 monocyclopentadienyl compounds of vanadium and alumoxanes in the presence of aromatic vinyl compounds as the solvent at temperatures of −30 C. to +80 C. By means of the process according to the invention, it is possible to straightforwardly produce solutions of polydiolefins, such as polybutadiene, having 1,2 unit contents of 10 to 30% in aromatic vinyl compounds, which solutions may then, for example, be further processed to yield ABS or HIPS.
