SEC chromatograms were recorded on a Shimadzu HPLC-IR liquid chromatograph, equipped with an LC-30AD SP pump, a SIL-20AC TH autosampler, a CTO-20A column oven coupled with an SPD-20A UV detector. Analyses were performed using a GPC KF-805L column. THF HPLC grade was used as isocratic elution solvent, with a flow rate of 1 mL.min -1 , an acquisition time of 14 min, and the polymer detection was performed at 260 nm. The temperature of the column oven was set at 30 °C. 1 µL of polymer solution in THF (5 mg•mL -1 ) was injected into the column. Calibration was done using Polystyrene standards with theoretical Mn of 2000 g•mol -1 , 5000 g•mol -1 , 9000 g•mol -1 , 17500 g•mol -1 , 30000 g•mol -1 and 50000 g•mol -1 purchased from Sigma Aldrich.
