Popis:	Experimental evidence has been found for associative phase separation in a mixture of a nonclouding hydrophobically modified poly(acrylamide) and sodium dodecyl sulfate. The phase separation is strongly dependent on the concentration of added Na 2 SO 4 . The phase separation region in the presence of salt decreases with increasing temperature. Clearing transition temperatures from the two-phase to the one-phase region are reported. Fluorescence measurements using pyrene as the luminescence probe, 1 H NMR spectra, and viscosity measurements show that the interaction between polymer and surfactant takes place also when no phase separation occurs
