Monomolecular Micelles Based on Amphiphilic Invertible Polymers

Using surface tension measurements, solubilization of dimethyl yellow dye and solvatochromic dye Et30, and fluorescence spectroscopy, amphiphilic polyesters containing alternated hydrophilic poly(ethylene glycol) fragments and lipophilic dicarboxylic acid or polytetrahydorfuran moieties in the polymer backbone have been shown to form monomolecular micelles in aqueous solutions at the concentrations of 10-7–10-4 %. These monomolecular micelles have been demonstrated to possess invertibility and respond to the change in a medium polarity.
