| Quantity | Value | Units | Method | Reference | Comment |
|---|---|---|---|---|---|
| S°solid,1 bar | 17.11 | cal/mol*K | N/A | Chang, 1977 | glass phase; Per monomer unit. Value is S-S0. |
| S°solid,1 bar | 15.56 | cal/mol*K | N/A | Lebedev, Rabinovich, et al., 1967 | glass phase |
Constant pressure heat capacity of solid
| Cp,solid (cal/mol*K) | Temperature (K) | Reference | Comment |
|---|---|---|---|
| 14.11 | 298.15 | Chang, 1977 | glass phase; T = 6 to 380 K. Value per monomer unit. |
| 14.33 | 298.15 | Lebedev, Rabinovich, et al., 1967 | glass phase; T = 58 to 300 K. Value per monomer unit. |
| 14.21 | 298. | Alford and Dole, 1955 | glass 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. |
