General conditions: 3.35 mmol diol, 3.35 mmol DMFD/DMTA, 1 mol % catalyst, 190 °C N2/1 h, 230 °C vacuum 1 mPa.

aPoly (PC/TPA) and poly (PC/FDCA) prepared in a vacuum for 3 h were subjected to purification by dissolving precipitation method.

bCopolymerization of PC-rich product mixture (PC, 82 and 1.13 %] obtained from catalytic funneling of the model mixture of 1 G/1 S (equimolar) with DMFD and DMTA (See Supplementary Note 3.4).

cPoly (PC/1/TPA) was prepared via copolymerization of lignin-derived PC/1 with cellulose-derived DMFD. (Supplementary Note 3.5).

dYield (%) = weight of collected product /weight of theoretical product × 100%.

eMolecular weight distribution was determined by GPC.

fT5% and T90% were determined by TGA characterization.

gTg was determined by DSC characterization.
