Popis:	The temperature dependences of the heat capacities of hydrated acrylamide and poly(acrylamide) complexes of cobalt nitrate are studied via high-precision adiabatic calorimetry at 6 to 300–380 K. The energy of combustion is estimated via isothermic calorimetry. This evidence makes it possible to calculate thermodynamic functions Cpℴ(T), Hℴ(T) − Hℴ(0), Sℴ(T), Gℴ(T) − Hℴ(0) at 0 to 300–380 K; the standard enthalpy of combustion, ΔcHℴ; and the thermodynamic parameters of formation, ΔfHℴ, ΔfSℴ, and ΔfGℴ, of monomer and polymer complexes composed of simple compounds at 298.15 K. The results are used for the estimation of enthalpy ΔpolHℴ, entropy ΔpolSℴ, and Gibbs function ΔpolGℴ of bulk polymerization for hydrated acrylamide complexes of cobalt nitrate at 0–300 K.
