STUDY OF THE THERMAL PROPERTIES FOR SINGLE CRYSTAL OF POLYBIS-(p-TOLUENE SULFONATE) OF 2,4-HEXADIYNE-1, 6-DIOL(PTS)
聚双(对甲苯磺酸)-2,4-己二炔-1,6-二醇酯(PTS)的热学性质

The thermal properties for PTS are studied by photoacoustic effect in temperature range 175-225 K. It is found that there is a peak of C3K at 200 K (here C3 and K are the specific heat and thermal conductivity of PTS, respectively), which shows crearly the existence of a second order phase transition in view of thermal propertis for the first lime. An anomalous thermal conductivity in the above temperature range is deduced from experiment results.
