Thermal conductivity of amorphous Teflon (AF 1600) at high pressure

The thermal conductivity. 2, of amorphous Teflon AF 1600 [poly( 1.3-dioxole- 4,5-difluoro-2,2-bisItrifluorometlly}l -co-tetrafluoroethylenel] has been measured tit pressures tip to 2 GPa in the temperature range 93 392 K. At 295 K and atmospheric pressure we obtained 2=0.116 W-m ʹ. K ʹ. The bulk modnlus was measured tip to 1.0 (JPa in the temperature range 150-296 K and the combined data yieklcd the following wdues for g=(? In 2 ? In p)/: 2.8 +0.2 at 296 K, 3.11• 0.2 at 258 K. 3.0 + 0.2 at 236 K, 3.4 + 0.2 at 200 K, and 3.4+__ 0.2 at 150 K.
