Abstract

Polymers and copolymers of conjugated dienes and aromatic vinyl compound which have a carboxyl end group and are present as salts, the salts containing metal cations or metal cation complexes which are bivalent or polyvallent and also a process for preparing such salts of polymers which contain carboxyl end groups and their use for modifying thermoplastic materials or as vulcanizable materials.
