These are new polyurethanes that significantly thicken an aqueous formulation with a low, medium and high shear gradient. The invention also concerns the compositions containing them and their uses in different formulations such as aqueous paints. ## Claims ### Claim 1 A water soluble polyurethane resulting from the condensation of: a monomer of formula (I) where R designates an alkyl group with 6 to 10 carbon atoms, a polyalkylene glycol, and a polyisocyanate. ### Claim 2 (depends on 1) The polyurethane according to claim 1, resulting from the condensation of: a monomer of formula (I), a polyalkylene glycol, a polyisocyanate, and an aliphatic alcohol having between 6 and 20 carbon atoms. ### Claim 3 (depends on 1) The polyurethane according to claim 1, resulting from the condensation of: a) 1% to 29% by weight of said monomer of formula (I), b) 70% to 98% by weight of said polyalkylene glycol, and c) 1% to 29% by weight of said polyisocyanate where the sum of these mass percentages is equal to 100%. ### Claim 4 (depends on 1) The polyurethane according to claim 1, resulting from the condensation of a) 3% to 7% by weight of said monomer of formula (I), b) 86% to 94% by weight of said polyalkylene glycol, and c) 3% to 7% by weight of said polyisocyanate where the sum of these mass percentages is equal to 100%. ### Claim 5 (depends on 1) The polyurethane according to claim 1, where the polylakylene glycol is polyethylene glycol the molecular mass by weight of which is 2,000 g/mol-20,000 g/mol. ### Claim 6 (depends on 1) The polyurethane according to claim 1, where the polyisocyanate is chosen from the group consisting of toluene diisocyanate, the toluene diisocyanate dimers, the toluene diisocyanate trimers, 1,4-butane diisocyanate, 1,6-hexane diisocyanate, isophorone diisocyanate, 1,3-cyclohexane diisocyanate, 1,4-cyclohexane diisocyanate, 4,4′diisocyanatodicyclohexylmethane, 1-methyl-2,4-diisocyanatocyclohexane, a blend of 1-methyl-2,4-diisocyanatocyclohexane and 1-methyl-2,6-diisocyanatocyclohexane, the biuret of hexamethylene diisocyanate, the dimers of the biuret of hexamethylene diisocyanate, the trimers of biuret of hexamethylene diisocyanate, and mixtures thereof. ### Claim 7 (depends on 1) The polyurethane according to claim 1, where R designates a group having 9 carbon atoms. ### Claim 8 (depends on 1) The polyurethane according to claim 1, resulting from the condensation of: a) 1 to 29% by weight of said monomer of formula (I), b) 70% to 98% by weight of said polyalkylene glycol, c) 1% to 29% by weight of said polyisocyanate, and d) 1% to 29% by weight of an aliphatic alcohol having between 6 and 20 carbon atoms, where the sum of these mass percentages is equal to 100%. ### Claim 9 (depends on 8) The polyurethane according to claim 8, resulting from the condensation of: a) 1% to 29% by weight of said monomer of formula (I), b) 70% to 98% by weight of said polyalkylene glycol, c) 1% to 29% by weight of said polyisocyanate, and d) 1% to 29% by weight of an aliphatic alcohol having between 10 and 15 carbon atoms, where the sum of these mass percentages is equal to 100%. ### Claim 10 (depends on 1) An aqueous composition comprising water and a polyurethane according to claim 1. ### Claim 11 (depends on 10) An aqueous composition according to claim 10, further comprising a surfactant. ### Claim 12 (depends on 10) An aqueous composition according to claim 10, further comprising an additive selected from the group consisting of a biocide, a solvent, an anti-foaming agent, a pH regulator, a coalescent agent and mixtures thereof. ### Claim 13 (depends on 10) An aqueous composition according to claim 10, comprising: 5% to 45% by weight of said polyurethane, 5% to 30% by weight of a surfactant, 25% to 75% by weight of water, and 0 to 5% by weight of an additive selected from the group consisting of a biocide, a solvent, an anti-foaming agent, a pH regulator, a coalescent agent, and mixtures thereof, where the sum of these mass percentages is equal to 100%.
