The melting temperature of the gels of the poly(vinyl alcohol) (PVA)/ethylene glycol (EG) system was measured. It was found that the temperature was independent of the thermal hysteresis. The apparent enthalpy of the fusion of the junction, DH, was 206 kJ/mol for a high molecular weight atactic PVA
The aim of this work was to establish whether the lifetime of the junction zones in the poly(vinyl alcohol)/ borate gels depended on the chemical composition or concentration of the constituents. It was found that the maximum in the distribution of lifetimes was about 0.3 s and independent of the po
## Abstract The light transmittance of the gels of poly(vinyl alcohol) (PVA)/phenol/water solutions was examined for the entire range of phenol/water content. Excellent transparency was found for the gels with phenol contents of 70β95 vol %. In full consideration of the results for the transparency
