METHYLATED polyethylene glycol MW 2000

wt%		log P (dynes/cm^2)

10.3		6.48
15.1		6.72
24.8		7.20
35.5		7.45

An equation that fits this data is the following.

log P = a + b * (wt%) ^ c

where a = 1.34, b = 3.66 and c = 0.14

Note that it should be applied only over the range of pressures measured.
