The data in Figure roughly collapse on a single line, supporting our analysis of the interaction parameters. Note that we have enforced a conversion of exactly 𝑝 = 0.95 in the simulations that serves as a benchmark for the experimental systems. Accordingly, the experimental data are not far from conversions around 𝑝 ≈ 0.95. We further conclude that the large swelling in CHCl3 results from the solvent quality and not from a lower conversion.
