Diene polymers (I) having, at the start of the polymer chain, tertiary amino groups (Ia), (Ib), (IIa) or (IIb) are new. Diene polymers (I) having, at the start of the polymer chain, tertiary amino groups of formula ((R1)(R2)N-CH-CH=CH 2) (Ia), ((R1)(R2)N-CH=CH-CH 2-) (Ib), (IIa) or (IIb), and, on the polymer chain ends, silane-containing carbinol groups of formula (-(R3)(R4)Si-C(R5)(R6)-A-OH) (III) or their metal salts or semi-metal salts are new. R1, R2 : alkyl, cycloalkyl, aryl, alkaryl or aralkyl groups, which contain heteroatoms (O, N, S or Si); Z : divalent organic group, which contains, in addition to C and H, heteroatoms (O, N, S or Si); R3-R6 : H, alkyl, cycloalkyl, aryl, alkaryl or aralkyl groups which contain heteroatoms (O, N, S or Si); and A : divalent organic group which contains, in addition to C and H, heteroatoms (O, N, S or Si). Independent claims are included for: (1) preparing (I); and (2) a vulcanizable rubber composition, comprising (I), antioxidants, oils, fillers, rubber and/or rubber auxiliaries. [Image].
