For size exclusion chromatography a system consisting of DEGASi GPC degasser (Biotech, This cycle was repeated three times. Glass transition temperatures (Tg) were determined from the inflection point of the second and third heating cycles using TA Instruments Universal Analysis 2000 software (v4.5A). Thermal analysis performed using STA 449 F3 thermal analyzer (Netzsch, Selb, Germany). The samples (10 mg) were added into aluminum oxide crucibles and heated under synthetic air from 30 °C to 1000 °C (10 °C/min) while detecting the mass loss.
