<p>The invention relates to a polymer having formula (I), wherein: P is a divalent polymer radical, on the condition that P is different from a polyoxypropylene radical; m is a number between 1 and 6; B is a monovalent, divalent, trivalent, tetravalent, pentavalent or hexavalent radical, said radical comprising generally between 1 and 44 carbon atoms per molecule; the divalent polymer radical P being such that the number-average molar mass Mn of the polymer of formula (I) is within a range of 400 to 8000 g/mol and such that the polymolecularity (Pd) of the polymer of formula (I) is within a range from 1.0 to 4.0. The invention relates to a method for the production of the polymer having formula (I). The invention also relates to a method for the production of polyurethanes, comprising the reaction of a polymer having formula (I) with a compound containing an amino group, as well as polyurethanes that can be obtained in this manner.</p> |
