Figure 2
The dynamic structure factor from an Mw = 36 kg mol−1 PE melt at 509 K as a function of time. The solid lines are a fit with the reptation model [equation (2)]. The Q values are from the top Q = 0.05, 0.077, 0.115 and 0.145 Å−1. The horizontal dashed lines display the prediction of the Debye–Waller factor estimate for the confinement size (see text). |
