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).
