Abstract
The paper presents results of measurements of evolution of the photoconductivity and the low-frequency electric permittivity of the mixed pTS-pFBS diacetylene single crystals during the thermally driven solid-state polymerization. The kinetics of the polymerization was found to be a function of the composition of the crystals, the rate constants in the induction and autocatalytic periods following different composition dependences. Changes in the kinetics of the photocurrent build-up essentially follow the changes in the polymerization kinetics. Temperatures of the phase transitions in the mixed crystals decrease with increasing concentration of pFBS, probably due to weaker dipole-dipole interactions between fluorobenzenesulfonyl side groups.
