A competition among additives for a place in the polymer matrix under levelling effect of the blending enthalpy was found. The competition apparently contradicts the entropy nature of the mixtures exhibiting accelerated desorption of the added compound from films in a glassy- or jelly-like state. The effects considered cannot be treated by statistical of thermodynamics of solutions and the theory of “the chaos elements in the close order range”. They are however, explainable by taking into account the specificity of the chain-sponge structure function. The processes of the equilibrium sorption of vaporized compounds by polymers are explained by the mechanism of structural entropic solvation and described by the equation of the micropore volume filling theory. |
