Abstract

PURPOSE:To prepare a furan resin having excellent dimensional stability, chemical resistance, etc., by reacting a specific furan compound with isopropenylphenol and/or its oligomer. CONSTITUTION:(A) A furan compound, e.g. furfuryl alcohol, furfural, furan, etc., is reacted with (B) isopropenylphenol and/or its oligomer I or II (n=0-50) in the presence of (C) an acid catalyst (e.g. sulfuric acid, p-toluenesulfonic acid, etc.). Preferably (A)/(B)=0.2-20 and (C)/(B)=0.01-25 in molar ratio. The reaction is preferably carried out at 40-150 deg.C for 1-5hr. The furan resin is preferably modified by reacting with (a) formaldehyde, (b) urea and formaldehyde, or (c) phenol and formaldehyde in the presence of an acid catalyst.
