PVP 10K

PVP Osmotic pressure data, (dynes/cm2) for PVP polymer solution (MW 10000).

Wt%Log P (dynes/cm2)
2.56.53

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.

PVA 20K

PVP Osmotic pressure data, (dynes/cm2) for POLYVINYLALCHOL (PVA) polymer solution (MW 10000).

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.
