Figure 4: Variation of the peak position, q*, in the structure factors 𝑆 P o l ( 𝑞 ) with polymer density 𝜌 P o l for (a) the PC system, (b) PA system, (c) PC system at various parameters of Yukawa-type potential (Yuk) and for a 6-12 type Lennard-Jones potential (LJ) and for the PA system at α = 1. The graphs are plotted in the double-logarithmic scale.
