Dependence of the Thermodynamic Characteristics of a Carbon Monoxide–Ethylene–Butene-1 Copolymer on the Concentration of Butane Fragments in the Macromolecules
2018
The heat capacity, temperatures and enthalpies of the physical transformations of a triple alternating copolymer of carbon monoxide with ethylene and butene-1 with a 46 mol % concentration of butane fragments are studied via adiabatic and differential scanning calorimetry in the region of 6−570 K. Its combustion energy in a condensed state at T = 298.15 K is measured calorimetrically. Standard thermodynamic functions of the copolymer in the region of T → 0 to 400 K and the thermodynamic characteristics of its formation at T = 298.15 K and synthesis within the range of T → 0 to 400 K are calculated. The dependences of the thermodynamic properties of the copolymer on the concentration of butane fragments in the macromolecules are obtained.
