A An elugram of P124 presented as the detected molar mass vs. elution volume before (black line) and after (red line) heating for 5 h at 55 °C. B The RMS conformation plot before (black line) and after (red line) heating for 5 h at 55 °C. Before the heating, fractions with a high molar mass and a uniform RMS can be observed. After heating, the aggregates are broken up to single chains, which exhibit a linear relation of RMS vs. molar mass
