Example text

After this correction from Fig. 9 quantitative agreement between both results is evident. 10 compares the same experimental data, with a best fit to the Rouse model (Eq. 19). 14 A- 1), while at higher Q important deviations appear. Similarly, the simulations cannot be fitted in detail with a Rouse structure factor. Recently this result was confrrmed by an atomistic computer simulation on PE molecules of different lengths. Again, at high Q the Rouse model predicts a too-fast decay for Spair(Q,t) [53].

5 Single chain structure factor from a PEE melt at 473 K. The numbers along the curves represent the experimental Q-values in [A- 1]. The solid lines are a joint fit with the Rouse model (Eq. 19).

The dashed line displays the Rouse prediction for infinite chains, the solid lines incorporate the effect of translational diffusion. The different symbols relate to the spectra displayed in Fig.

Thereby the Gaussian assumption is implied. J 0 50 100 150 200 timet/ns Fig.
