Thermodynamic properties of organoelement polymers

The temperature dependences of heat capacity and the characteristics of the phase and relaxation transitions of 36 organoelement polymers belonging to 11 different classes are discussed. The thermodynamic functions C-p(o)(T), H-o(T)-H-o(0), S-o(T)-S-o(0), and G(o)(T)-H-o(0) at T = 298.15 K and stand ard pressure,as well as the temperatures, enthalpies, entropies, and other thermodynamic parameters of the physical transitions are determined. The ef fects of the composition and structure of the polymers on their thermodynam ic parameters are described. The numerical values of all the parameters are derived from the data of precise calorimetric measurements.
