摘要
The temperature dependence of heat capacity of triple alternating copolymer ethylene-carbon monoxide-propylene with 23.4 mol.% of propane fragments was studied for the first time by adiabatic and dynamic calorimetry over the range of 6-480 K. The energy of copolymer combustion at 298.15 K was measured in isothermic calorimeter with stationary bomb. The thermodynamic parameters of phase and physical transitions were determined. The standard thermodynamic functions C (p) (au <)(T), H (au <)(T) - H (au <)(0), S (au <)(T) - S (au <)(0) and G (au <)(T) - H (au <)(0), for region from T -> 0 to 320 K, the standard enthalpy of combustion and thermodynamic characteristics of formation of the studied compound at 298.15 K were calculated from the experimental data. The thermodynamic parameters of alternating copolymerization of CO with ethylene and propylene at standard pressure over 0-300 K region were detemined.
