- Abstract
With the use of polarized luminescence, relaxation times characterizing the intramolecular mobility of luminescent labeled copolymers of 2-deoxy-2-methacrylamido- D-glucose and unsaturated acids in solutions are determined in both nonionized and ionized states. Elements of the secondary structure typical for poly(methacrylic acid) are formed in copolymers with a high content of methacrylic acid (≥50 mol %) in their nonionized state. This structure is destroyed during ionization. Equilibrium stability constants for complexes of the copolymers with cationic surfactants are determined. Quantitative characteristics of the effects of the surfactant and copolymer structures and the ionic strength of solution on complex formation are estimated.
