    • Poly(n -butyl methacrylates) with different molecular weights (17) show a change in the X-ray patterns (decrease of the intensity and shift to higher q -values of the position of the first peak) for oligomers with less than 10 monomers. However, the first peak indicative for nanodomain formation is present even in chains of only 6 monomers. The polymers here simulated have a relatively small degree of polymerization. Though a direct quantitative mapping to real polymers is not possible, the simulated chains are obviously long enough to develop the characteristic pattern attributed to nanophase segregation.

    • Unlike for hard-sphere interactions, (47, 48) monomers in the simulated model can be penetrated due to the softness of the WCA potential (eq 1). Thus, it might be that the energetic contribution to the free energy for segregation is not strictly zero (though clearly negligible in comparison with the entropic contribution).
