Fig. 3: Characteristics of the biomass-derived decomposable polymers.

A Structures of P1–P6. B Thermogravimetric analysis (TGA) thermograms of P1–P6. C Differential scanning calorimetry (DSC) thermograms of P1–P6. Heat flow is shown in the endothermic down direction. D Thermal properties of each polymer. Polymerization conditions, P1: 0.096 mM M1 in HFIP initiated by 100 mol.% PIDA at 25 °C for 60 min. P2 and P4–P6: 0.384 M monomer in acetonitrile (MeCN) catalyzed by 1 mol.% of the Ir-F photocatalyst at 25 °C for 60 h. P3: 0.384 M M3 in MeCN catalyzed by 1 mol.% of the Ir-F photocatalyst at 25 °C for 17 h.
