Tga dsc1 apparatus

Thermogravimetric analysis (TGA) measurements were performed by means of a TGA/DSC1 apparatus (Mettler Toledo, Greifensee, Switzerland) equipped with STAR software. The experiments were carried out under air flow (40 mL min⁻¹) at the temperature range from 25 to 850 °C with a heating rate of 5 °C min⁻¹.

The ¹H and ¹³C NMR spectra were recorded on a Bruker AVANCE 400 or on Bruker Avance III (600 MHz) spectrometers (Bruker Corporation, Billerica, MS, USA). CDCl₃ (Cambridge Isotope Laboratories, Inc., Tewksbury, MA, USA, D 99.8%) was used as purchased. The chemical shifts are reported in ppm relative to the solvent residual peaks.
Size exclusion chromatography (SEC) of polymer samples was performed using an Agilent PL-GPC 220 chromatograph equipped with a PLgel column (Agilent Technologies, Santa Clara, CA, USA) and THF was used as the eluent (1 mL/min). The measurements were recorded with universal calibration based on a polystyrene standard at 40 °C.
Differential scanning calorimetry (DSC) experiments were performed on the TGA/DSC1 apparatus (Mettler Toledo, Columbus, OH, USA).

Thermal analysis (thermogravimetry and differential scanning calorimetry) were carried out simultaneously using TGA/DSC1 apparatus (Mettler Toledo, Columbus, OH, USA). Samples were fractioned, weighed (not less than 10 mg) and placed into 100 µL aluminum crucibles. The analyses were performed at an air atmosphere in a temperature range from 30 to 600 °C, with a heating rate of 10 °C per minute.
