PVP Osmotic pressure data, (dynes/cm2) for PVP polymer solution (MW 10000).
| Wt% | Log P (dynes/cm2) |
| 2.5 | 6.53 |
| 5.0 | 6.55 |
| 7.5 | 6.67 |
| 10.0 | 6.73 |
| 12.5 | 6.79 |
| 15.0 | 6.85 |
| 17.5 | 6.92 |
| 20.0 | 6.97 |
| 22.5 | 7.02 |
| 25.0 | 7.09 |
| 27.5 | 7.13 |
| 30.0 | 7.22 |
The equation that fits the data is the following:
log P = 0.025 (wt%) + 6.468
Note: This equation should only be applied over the range of pressures measured.
