Star polymers, and their preparation

Star polymers obtainable by polymerization of vinylaromatic monomers with a branching monomer unit containing at least two vinylaromatic functional radicals in the presence of a catalyst obtainable from A) a transition-metal complex from sub-group II to VIII, B) a cation-forming agent and C), if des...
