Figure 4.

Radius of gyration scaled over the monomer diameter a against interaction parameter λ for a linear chain polymer with N = 20. The black curve shows the polymer with an interaction potential exponent n = 12, while the blue curve depicts n = 6. The good solvent regime of the polymer with n = 12 is highlighted by a green background, the poor solvent regime is highlighted in red. The golden bar in the middle shows the area in which the Θ point of the polymer for n = 12 is located. The dotted curves represent nonphysical regimes for the interaction parameter λ due to solvent accumulation, as explained in the text.
