文摘

The temperature dependence of heat capacity of the amorphous poly-1H,1H,5H-octafluoropentyl acrylate between T = (6 and 350) K was measured by a adiabatic calorimeter. In the interval 225 K to 242 K the glass transition was detected and this thermodynamic parameters were determined. On the basis of the experimental data, the standard thermodynamic functions, namely, the heat capacity, enthalpy, entropy and Gibbs function of heating were calculated for the polymer in the interval from T 鈫?0 K to 350 K. The low-temperature (T < 50 K) dependence of the heat capacity was used to evaluate the topology鈥檚 type of polymer structure.
