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

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.
