Abstract

Relationships between the kinetic parameters for free-radical recombination in polymers and low-molecular weight crystals and the pressure, volume and temperature have been studied. Experimental values for the activation volumes and energies of chemical reactions in solids have been shown to coincide with the corresponding V∗ and E values in small-scale molecular dynamics. A relationship is established between the activation recombination parameters and the compound's coefficients of compressibility and thermal expansion. Equations are obtained relating the state parameters, reaction activation parameters and macro-characteristics of condensed media.
