Figure 5 Dynamic structure factor of a centre-labelled 25 kg mol-1 PE chain (red symbols) compared to a fully labelled chain (green symbols) of the same overall molecular weight. Q values (in nm-1): 0.5 (squares), 0.96 (circles), 1.15 (triangles). Lines: for centre-labelled chain, pure reptation model [equation (2), red]; for fully labelled 25 kg mol-1 chain (green) CLF was considered (see Lyamichev et al., 1993).
