A method for producing a hydrophobically associative polymer comprising: (a) forming a monomer solution comprising surfactant, water, a hydrophobic ethylenically unsaturated monomer, a hydrophilic monomer selected from nonionic ethylenically monomers, cationic ethylenically unsaturated monomers, anionic ethylenically unsaturated monomers or mixtures thereof, (b) forming a salt solution comprising a multivalent salt, stabiliser and water, (c) mixing the monomer solution and salt solution to form a mixed solution, (d) charging the mixed solution with an initiator, thereby polymerisation the monomers to form the hydrophobically associative polymer in a dispersion. Also disclosed is an aqueous dispersion containing the hydrophobically associative polymer formed by the method. The aqueous dispersion containing the hydrophobically associative polymer may be used in a paint formulation, in a mobility control fluid useful in enhanced oil recovery, in a secondary or tertiary oil recovery system, in an enhanced oil recovery method, in a cementious composition, in an oil well drilling mud formulation, in a fracturing fluid formulation, in a wastewater treatment system, or in a dewatering sludge system.
