PVP Osmotic pressure data, (dynes/cm2) for POLYVINYLALCHOL (PVA) polymer solution (MW 10000).
| Wt% | Log P (dynes/cm2) |
| 2.0 | 6.39 |
| 4.0 | 6.42 |
| 6.0 | 6.45 |
| 8.0 | 6.47 |
| 10.0 | 6.49 |
| 12.0 | 6.51 |
The equation that fits the data is the following:
log P = -0.001 (wt%)2 + 0.025 (wt%) + 6.327
Note: This equation should be applied only over the range of pressures measured.
