Abstract

AbstractThermodynamic properties of norborneneSystem: name: bicyclo[2.2.1]hept‐2‐ene. and polynorbornene, viz. isobaric heat capacity of the monomer and polymer between 10 and 330–400 K, parameters of physical transitions of the monomer and polymer, and energy of combustion for the polymer were studied by means of precise adiabatic and isothermal calorimetry. From the experimental data, the thermodynamic functions H°(T)–H°(0), S°(T) and G°(T)–H°(0) in the range of 0 to 330–400 K as well as enthalpies of combustion and thermochemical quantities of formation ΔH, and ΔS for polynorbornene were calculated. The results were used to calculate enthalpies, entropies and Gibbs functions of bulk polymerization for norbornene between 0 and 330 K and to evaluate the ceiling temperature of polymerization.
