Claim:
1. An alkoxylation product with an intrinsically reduced viscosity, said alkoxylation product comprising a polymer of formula (I) where the fragments M, D, T and Q are linked not to one another, but instead with one another, via the groups UR and/or AP, and the groups UR and AP are linked, not to one another, but instead with one another, correspondingly, via the fragments M, D, T or Q, where i=0 to 16, j=0 to 10, k=0 to 6, l=0 to 4, u=0 to 17, v=0 to 6, with the proviso that i+j+k+l>=1, M independently at each occurrence is an oxygen-radical-carrying hydrocarbon radical having a minimum numerical molar mass of 88 g/mol, or is a radical of formula (Ia), or of formula (Ib), or of formula (Ic) where a=0 to 1000, b=1 to 1000, c=0 to 1000, d=0 to 1000, w=an integer from 0 to 1000, x=0 to 1000, y=an integer from 0 to 500, e=1 to 10, f=0 to 2, g=1 to 3, with the proviso that g+f=3 and g is at least 1, h=0 to 10 and with the proviso that the various monomer units of the fragments with the indices a, b, c, d, w, x and y are freely permutable among one another, and each of the groups with the indices w and y cannot follow itself or the other respective group, and where R R R R R R R R R R where R where R and, if j, k and I are each=0, then M must=formula (Ia); and where, for the fragments D, T and Q: D is a polyether radical PE with t being 2, T is a polyether radical PE with t being 3 and Q is a polyether radical PE with t being 4, where PE independently at each occurrence is a polyether radical with the formula where t=2 to 4, and D and where D with a to h, w, x and y and R with the proviso that the sum of all the indices a from formula (Ia) and formula (II) must be greater than or equal to 1, wherein the sum of all the indices x from formula (Ia) and formula (II) must be greater than or equal to 1, UR independently at each occurrence are identical or different divalent radicals of the form -U-D or a monovalent radical of the form D or a trivalent radical of the form D or a tetravalent radical of the form D where U is a —C(O)—NH— group which is bonded via the nitrogen to D and D and D and D or, if polyisocyanates with the structural units D
