The thermal solid state polymerization was analysed for topospecifically deuterated derivatives of 2,4-hexadiynylene di-p-toluenesulfonate (PTS). Deuteration of the methylene groups close to the diacetylene-monomer triple bonds influences drastically the length of the induction period and the reaction-rate constants in the autocatalytic period. These peculiarities were investigated by the combination of dielectric permittivity measurements with differential scanning calorimetry and gravimetrical analyses of the solid state polymerization.
