Heat Capacity and Other Thermodynamic Properties of Linear Macromolecules. VIII. Polyesters and Polyamides

Heat capacity of polyglycolide, poly(ε-caprolactone), poly(ethylene terephthalate), poly(ethylene sebacate), polyglycine, poly(L-alanine), poly(L-valine),nylon 6, nylon 6.6 and nylon 6.12 is reviewed on the basis of measurements on 35 samples reported in the literature. All heat capacity data are compiled and a set of recommended data have been derived for each polymer. Crystallinity dependence is critically evaluated for poly(ethylene terephthalate). Enthalpy and entropy functions are calculated for amorphous poly(ethylene terephthalate). This is the eighth paper in a series of publications which will ultimately cover all heat capacity measurements of linear macromolecules.
