Ss. Rashidova et al., CALORIMETRIC STUDIES OF THE HEATS OF INTE RACTION BETWEEN METHYLCELLULOSE AND POLY(VINYLPYRROLIDONE), Vysokomolekularnye soedinenia. Seria A, 39(3), 1997, pp. 556-558
Calorimetry was used to determine the heats of interaction between met
hylcellulose and poly(vinyipyrrolidone) in their blends of various com
positions. A strong adhesive interaction between the components was di
scovered in the blends with a high content of poly(vinylpyrrolidone).
In contrast, this interaction is virtually absent in the blends rich i
n methylcellulose.
