- Аннотация: Mixtures of polyvinyl alcohol and amber acid of different composition were subjected to plastic deformation under the pressure of 1.5 GPa at the equipment of the Bridgman-anvil type and the DSC method was used to study heat processes in nondeformed and deformed samples. It is shown that two processes occur simultaneously in PVA under heating: the endothermal process of decomposition of intermolecular bonds and mass decrease related to loss of adsorbed water. After plastic deformation, a decrease in the enthalpy of melting occurred in both components of the PVC–amber-acid mixtures. A low-temperature phase with Tmelt 30–40° C lower than in the initial polymer was formed in the acid and a decrease in the relaxation process enthalpy was observed in the polymer.
