The non-bonded pair interaction between monomers reflects the quality of the implicit solvent towards the polymer, i.e., varying solvent and polymer temperature. Our simple polymer model without solvent and explicit T-dependent interactions exhibits a UCST, while all qualitative trends including LCST are reflected, however, in inverse manner. LJ potentials with ε mer between 0.1 k B T and 0.9 k B T are used when scanning for the near-critical (collapse transition) solvent condition.
