Consideration of the natural rubber swelling into organic solvents on the basis of free energies linearity principle.

The swelling of the polymers into solutions represents by itself the complicated process depending on their different properties. That is why the swelling degree can not be determined via any one physical-chemical property of the solvent. The adequate relationship between the swelling degree and the properties of solvents can be obtained only under condition of taking into account the all acting factors by means of the linear multi-parametric equations.
