Abstract

Block polymers of vinylaromatic compounds and conjugated dienes which possess acidic terminal groups, are present in the form of lithium salts and form an aluminum complex. A process for the preparation of such complexes and the use of these block polymer complexes as molding materials and for modifying thermoplastic materials.
