ALPHA-OMEGA-FUNCTIONALIZED POLYMERS

1. A functionalized diene polymer having at least one first functional group and at least one second functional group wherein the first functional group is selected from terminal groups, side groups and combinations thereof and wherein the second functional group is a terminal group, wherein the first functional group (i) comprises at least one unit derived from a functionalizing monomer represented by formula (1) wherein R1, R2, R3 are selected from hydrogen and methyl with the proviso that at least one of R1, R2 and R3 is hydrogen, preferably R1, R2, and R3 are all hydrogen, n is 1, 2, 3, 4 or 5, each R4 is selected independently from an aliphatic, or aryl aliphatic residue having from 3 to 30 carbon atoms and wherein R4 comprises at least one tertiary amine group if n is 1 and in case n is 2 to 5 at least one of the residues R4 comprises at least one tertiary alkyl amine group; or (ii) wherein the first functional group is obtained by using a polymerization initiator of the general formula N(R1)(R2)(R3M), wherein R1 and R2 are identical or different from each other and are selected from linear or branched saturated alkyls and R3 is a saturated, linear or branched alkyl carbanion and M is an alkali cation, and wherein the second functional group is a terminal group and comprises at least one group selected from -COOX; -OX; -SX, a plurality thereof and combinations thereof, wherein X represents hydrogen or a cation, and wherein the functionalized diene polymer is a homopolymer or a copolymer of a conjugated diene and wherein the conjugated diene is selected from the group consisting of butadiene, isoprene, isoprene, 1,3-pentadiene, 2,3-dimethylbutadiene, 1-phenyl-1,3-butadiene, 1,3-hexadiene, preferably butadiene. Also provided are methods for producing the polymers, articles obtained from the polymer and methods for making articles with the polymer. 1. Polymère diénique fonctionnalisé présentant au moins un premier groupe fonctionnel et au moins un deuxième groupe fonctionnel, le premier groupe fonctionnel étant choisi parmi les groupes terminaison, les groupes latéraux et leurs combinaisons, et le deuxième groupe fonctionnel étant un groupe terminal, le premier groupe fonctionnel (i) comprenant au moins une unité issue d'un monomère de fonctionnalisation de formule (1) dans laquelle R1, R2, R3 sont choisis parmi l'hydrogène et le méthyle, à condition qu'au moins un des R1, R2 et R3 soit de l'hydrogène, de préférence R1, R2 et R3 sont tous de l'hydrogène
