Provided are [1] a furan resin comprising a repeating unit represented by the following general formula (1); and [2] a method for producing a furan resin, comprising reacting a specific furan compound and a specific carbonyl compound in the presence of an acid catalyst:
wherein R1, R2, R3 and R4 each independently represent a hydrogen atom, or an organic group having 1 to 8 carbon atoms which may contain a hetero atom; and R1 and R2, and R3 and R4 may be connected to each other to form a cyclic structure.
本发明提供了[1]一种呋喃树脂,该树脂由以下通式(1)代表的重复单元组成;以及[2]一种生产呋喃树脂的方法,该方法包括在酸催化剂存在下使特定的呋喃化合物和特定的羰基化合物发生反应:
其中 R1、R2、R3 和 R4 各自独立地代表一个氢原子或一个具有 1 至 8 个碳原子的有机基团,该有机基团可含有一个杂原子;R1 和 R2 以及 R3 和 R4 可相互连接以形成环状结构。
