Polymer vulcanizate and process for the production thereof

The invention relates to rubber blends containing said at least one solution-polymerized rubber containing hydroxyl groups, synthesized from diolefins and vinylaromatic monomers, wherein said at least one solution-polymerized rubber containing hydroxyl groups contain in the region of 0.1 to 5 wt. % of bonded hydroxyl groups, to a process for their preparation and to their use for the production of all kinds of moldings.
