Amorphous polyester from bio-based bis-furan assembly

Polymers, including Polyesters and Polycarbonates comprising residue of bis-furan diol, which is produced from renewable furfural feedstock and methods of making and using of those polyesters and polycarbonates are described. The method includes reacting a bis-furan diol with a dicarboxylic acid in the presence of a carbodiimide to produce the bis-furan containing polymers. In certain embodiments, the dicarboxylic acid is succinic acid; the bis-furan diol is the 5,5'-(propane-2,2-diyl)bis(furan-2,5-diyl) dimethanol and the carbodiimide is of N,N-diisopropylcarbodiimide.
