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.
本发明描述了包含双呋喃二醇残留物的聚合物,包括聚酯和聚碳酸酯,双呋喃二醇由可再生糠醛原料生产,还描述了制造和使用这些聚酯和聚碳酸酯的方法。该方法包括在碳化二亚胺存在下使双呋喃二醇与二羧酸反应,生成含双呋喃的聚合物。在某些实施例中,二羧酸是琥珀酸,双呋喃二醇是 5,5′-(丙烷-2,2-二基)双(呋喃-2,5-二基)二甲醇,碳二亚胺是 N,N-二异丙基碳二亚胺。
