Constant pressure heat capacity of solid

Cp,solid (J/mol*K) Temperature (K) Reference Comment
59.03298.15Chang, 1977glass phase; T = 6 to 380 K. Value per monomer unit.
59.96298.15Lebedev, Rabinovich, et al., 1967glass phase; T = 58 to 300 K. Value per monomer unit.
59.47298.Alford and Dole, 1955glass phase; T = 253 to 393 K. Cp calculated from equation. Cp(cal/g*K) = 0.2092 + 7.29x10-4t, where t<60°C for L-38 PVC, Cp(cal/g*K) = 0.2048 + 8.46x10-4t, where t<60°C for annealed PVC.
