✦ Synopsis

Cross-linked copolyesters containing kraft iignin were synthesized with sebacoyl chloride and terephthaloyl chloride by bulk polymerization. Polyethylene glycol was used as co-monomer and solvent for lignin. The effects of COC1/OH ratio, percentage of kraft lignin and molecular weight of PEG on the yield and thermal properties of these thermosets were investigated.
