Compositionally homogeneous modified polyacrylamides were synthesized by micellar copolymerization leading to hydrophobically associating polymers with a large range of viscosifying properties. The strength of the hydrophobic associations depends on the structure of the hydrophobic comonomer and its distribution. Hydrophobic comonomers with a bulky structure lead to particularly strong
