Claim Text:
1. A polymer obtained by a process which comprises the following steps: a) polymerization of at least one alkenyl aromatic monomer, at least one conjugated diene monomer, and at least one monomer containing at least one silyl hydride moiety; b) hydrogenation of the original dienic unsaturations of the polymer obtained in the previous step; and c) functionalization of some or all of the silyl hydride moieties available with one or more substrates having alkene or alkyne moieties via a hydrosilylation reaction in the presence of a catalyst; wherein the functionalization step c) is carried out either after or before the hydrogenation step b); or a) polymerization of at least one alkenyl aromatic monomer, at least one conjugated diene monomer, and at least one monomer containing at least one silyl hydride moiety; and b) hydrogenation of the original dienic unsaturations of the polymer obtained in the previous step.
