The solvent diffusion process with a variable diffusion coefficient was examined for the case of solvent desorption from polymer films. The thermoactivation theory of diffusion in polymers served as the basis for the formulation of an integral equation in which the parameters: time, temperature and concentration of residual solvent were correlated with physical constants of the system. The equation is valid in a wide range of temperatures for binary and ternary systems. The limit of applicability, the physical meaning of the constants were examined as well as different modifications of the equation. The specific nature of the interaction between polymer and solvent is manifested in a dependence of activation energy of diffusion on the quantity of residual solvent, however the physical meaning of the integral equation remains unchanged. The integral equation was also applied for the machine casting or plastic film from solution, and therefore can be used for guiding the production of films with specific physical and mechanical properties. |
