  This report documents microstructural features of CH3(CH2-O-CH2)mCH3
dissolved in water and n-hexane for m = 11, 21, and 31. Probability densities
for end-to-end distance, and the associated potential-of-mean-force (pmf), are
more revealing of chain microstructures than are the corresponding results for
the radii of gyration. For water, the pmf identifies three distinct regions:
loop-closure, globule, and high-extension regions. The globule region affirms a
water-swollen chain, and is not evident in the n-hexane results. Chain C-atom
density profiles from the chain centroid are also different in the water and
n-hexane cases. For n-hexane (but not water), the density profiles are similar
for the different chain lengths when the distances are scaled by the observed
<Rg^2>^{1/2}. For water (but not n-hexane) and the smaller chains considered,
the carbon material exhibits a distinctive enhanced concentration, or internal
condensation, at the centroid core of the structure.
