Hydrophobic association of hydrophobically modified polyacrylamide in aqueous solutions was studied by fluorescence spectroscopy using pyrene as a probe. It is shown that an increase in the amount of associating n-nonylacrylamide units in a polymer leads to the increase in the amount of hydrophobic associates, with the average size of one associate remaining unchanged. Similar regularities are observed in a salt medium as well (in the presence of sodium chloride), however, in this case the average size of associates is much larger.
