The present invention relates to a process for preparing hydrophobically associating macromonomers M and to the novel macromonomers prepared by means of the process according to the invention. The macromonomers M comprise a copolymerizable, ethylenically unsaturated group and a polyether structure in block form, the latter consisting of a polyethyleneoxy block and a hydrophobic polyalkyleneoxy block consisting of alkyleneoxy units having at least 4 carbon atoms. Optionally, the macromonomers M may have a terminal polyethyleneoxy block. The macromonomers prepared by the process according to the invention are suitable for reaction with further monomers, especially with acrylamide, to give a water-soluble, hydrophobically associating copolymer.

The present invention relates to a process for the alkoxylation of a first polymer comprising at least one monomer unit having NH groups and optionally NHgroups, wherein the first polymer has a molecular weight Mof at least 500 g/mol, comprising the steps of (a) reacting the first polymer with alkylene oxide in a reaction mixture comprising a solvent until the average degree of alkoxylation of each NH group and each optional NHgroup, calculated as two NH groups, is from 0.75 to 1.25; (b) adding a second polymer of formula (I), wherein R is a linear or branched alkyl group having from 1 to 20 carbon atoms, each R' is independently a linear or branched alkyl group having from 1 to 20 carbon atoms or hydrogen, each n is independently from 1 to 5 and m is from 5 to 40, to the reaction mixture of step (a); (c) at least partially removing the solvent from the reaction mixture of step (b); and (d) further reacting the reaction mixture of step (c) with alkylene oxide at a given temperature until the average degree of alkoxylation of each NH group and each optional NHgroup, calculated as two NH groups, of the first polymer is from 2 to 40. The present invention also relates to a polymer composition obtainable from that process and the use of such a polymer composition.
