Résumé / Abstract

Polymer derivatives of glycine, β-alanine, γ-aminobutyric and ε-aminocaproic acids were obtained in an alkaline medium by reacting excess of the above compounds with poly(N-vinyl pyrrolidone), containing 10 mol % epoxy groups. Degree of substitution of epoxide groups reached 78-87 % and grew with an increase in the hydrocarbon chain length of the amino acid. Amino acid polymeric derivatives behaved as weak polyelectrolytes, moreover, their pKb and pKa values varied in the same order as for their low-molecular-mass counterparts.
