Time evolution of the local density of NiPPA molecules, ΔN(x, t), for the trajectories starting from a well-mixed configuration at (a) 340 K, (b) 320 K, and (c) 300 K and those starting from a phase-separated configuration at (d) 340 K, (e) 320 K, and (f) 300 K; (g) Local densities of NiPPA molecules, ΔN(x, t), and water molecules, ΔNW(x, t), in a state of the liquid–liquid phase separation at 340 K, as obtained at t = 200 ns in trajectory (a); Snapshots of (h) NiPPA molecules and (i) water molecules in the same state as (g).
