CHEMICAL THERMODYNAMICS AND THERMOCHEMISTRY Thermodynamics of an Alternating Carbon Monoxide-Ethylene- Propylene Copolymer in the Region of T → 0 to 500 K

The heat capacity of a ternary alternating carbon monoxide-ethylene-propylene copolymer with a content of -CO-CH2-CH(CH3)- units of 13.3 mol % and the temperatures and enthalpies of its physical conversions are studied by adiabatic and differential scanning calorimetry in the region of 6-500 K. The com� bustion energy of the copolymer in the condensed state is measured calorimetrically at 298.15 K. The ther� modynamic functions in the region of T → 0 to 455 K and the thermodynamic characteristics of the forma� tion of this copolymer at T = 298.15 K and its synthesis within the range of T → 0 to 300 K are calculated.
