%X The thermal expansion coefficients (along and normal to the chain direction) of PTS have been measured by differential parallel-plate capacitances from 77 K to 273 K. A sudden change near the phase transition temperature 195 K and a negative expansion coefficient near 200 K along the chain direction have been observed. The causes of these result are discussed qualitati-vly.
