Abstract: The conductivity in bis-(p-toluene sulfonate) of 2,4-hexadiyne-l,6-diol(TS) and its polymer PTSsingle crystal was measured by means of a special device at a range of temperature from 77Kto 373K (353Kfor TS). Anomalies of conductivity of TSand PTSalong c-axes which are the directions of polymer chains of PTSat the temperature corresponding to their low temperature phase transition were observed.The temperatures of phase transition in TSobtained from anomalies of conductivity are 163Kand 208K.
