The present invention relates to diene polymers or diene copolymers in which the diene polymers or diene copolymers at the polymer chain starts tertiary amino groups of the formula (Ia), (Ib), (IIa) or (IIb)nhave, whereinnR 1, R 2 are the same or different and are alkyl, cycloalkyl, aryl, alkaryl and aralkyl radicals which may contain heteroatoms such as O, N, S and / or Si,nZ is a divalent organic radical which, in addition to C and H, may contain heteroatoms such as O, N, S and / or Si,nand at the polymer chain ends silane-containing carbinol groups of the formula (III)nor their metal salts or their semi-metal salts, whereinnR 3, R 4, R 5, R 6 are the same or different and represent H, alkyl, cycloalkyl, aryl, alkaryl and aralkyl radicals which may contain heteroatoms such as O, N, S and / or Si,nA is a divalent organic radical which, in addition to C and H, may contain heteroatoms such as O, N, S and / or Si. |
