Autor: S. M. Yugai, M. Yu. Yunusov, G. V. Nikonovich, N. D. Burkhanova, N. L. Voropaeva, S. Sh. Rashidova, R. Yu. Milusheva
Publikováno v: Chemistry of Natural Compounds. 36:258-262
Physical and physicochemical methods are used to study a blend based on industrial crab chitosan and polyvinylpyrrolidone over a wide composition range. Thermodynamic data indicate that this pair of polymers is compatible at certain component ratios.
