Abstract/Description: | Polymers, including polyesters and polycarbonates comprising residue of bis-furan diol, which is produced from renewable furfural feedstock, and methods of making and using 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. |
