Titrational behaviour of poly(N‐vinylpyrrolidone‐co‐maleic acid)
1985
Aqueous acid-base titration measurements were made on alternating copolymer, poly(N-vinylpyrrolidone-co-maleic acid). It was found, that P (NVP-co-MAc) behaves as a monobasic polyacid in potentiometric titration. Continuous pH-induced conformational transition of polymer chains occurred during titration. A novel method, densitometric titration, has been developed to measure chain conformation transition found potentiometrically.
