Abstract:
1. A method for producing a polynuclear poly(formylphenol) expressed by General Formula (2), characterized in that a polynuclear polyphenol expressed by General Formula (1) is caused to react with hexamethylene tetramine in the presence of an acid, and then the obtained reaction product is hydrolyzed: wherein all Rs may be the same or different and respectively represent a hydrogen atom or aromatic hydrocarbon group, hydroxyl group, or aliphatic hydrocarbon group that may have an ether group; R 1 , R 2 and R 3 may be the same or different and respectively represent a hydrocarbon group, hydrocarbon group containing oxygen atom, hydroxyl group, halogen group or halogenated hydrocarbon group; a and c respectively indicate an integer of 0 or 1 to 3, while b indicates an integer of 0, 1 or 2; l and n respectively indicate an integer of 1 to 3; m indicates an integer of 0, 1 or 2; X indicates a bond group or single bond; and Y indicates a bivalent alkylene group; wherein R 1 , R 2 , R 3 , a, b, c, l, m, n, X and Y indicate the same things represented by the corresponding symbols in General Formula (1), wherein the CH 2 OR's in General Formula (1) are converted into the CHO's in General Formula (2).
