Abstract:

The heats of combustion for 47 commercial and developmental polymers of known chemical structure were determined using an oxygen bomb calorimeter according to standard methods. The experimental results were compared to thermochemical calculations of the gross heat of combustion from (1) oxygen consumption and (2) group additivity of the heats of formation of products and reactants. The polymers examined were thermally stable, char-forming thermoplastics and thermoset resins containing a significant degree of aromaticity and heteroatoms including nitrogen, sulfur, phosphorus, silicon, and oxygen in linear and heterocyclic structures. The gross heats of combustion calculated from polymer enthalpies of formation and oxygen consumption thermochemistry were within 4 and 5 percent, respectively, of the experimental values from oxygen bomb calorimetry. The heat released by combustion per gram of diatomic oxygen consumed in the present study was E = 13.08 ± 0.87 kJ/g-O2 for polymers which combusted completely (n = 46). This value is indistinguishable from the universal E = 13.1 kJ/g-O2 used in oxygen consumption calorimetry.
