The heat capacityCpo of polypropanal was studied in a vacuum adiabatic calorimeter between 11 and 330 K, and in an ADKTTM automatic differential calorimeter from 320 to 370 K. The thermodynamic parameters of melting and glass transition of polypropanal were also determined. From the results, the thermodynamic functions of the polymer were calculated in the range 0 K to 360 K. The enthalpy of depolymerization of polypropanal to the starting monomer was measured in a DAK-1-1 differential automatic microcalorimeter. From the results of this study and literature data on the thermodynamic properties of propanal., the enthalpy, entropy and Gibbs function of bulk polymerization of propanal were estimated from 0 K to 330 K. Ceiling limiting temperatures of transitions of the liquid monomer to crystalline and high-elasticity polymer were determined.
