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.
本文描述了包括聚酯和聚碳酸酯在内的聚合物,其中包含从可再生糠醛原料生产的双呋喃二醇残留物,并描述了制备和使用这些聚酯和聚碳酸酯的方法。该方法包括在卡波二亚胺的存在下,将双呋喃二醇与二羧酸反应,以产生含有双呋喃的聚合物。在某些实施例中,二羧酸为琥珀酸;双呋喃二醇为5,5'-(丙烷-2,2-二基)双(呋喃-2,5-二基)二甲醇,卡波二亚胺为N,N-二异丙基卡波二亚胺。
