Abstract:
1. A polynuclear poly(phenol) family expressed by general formula (1) below: (in the formula, R 1 s are each independently an alkyl group with 1 to 8 carbon atoms, alkoxyl group with 1 to 8 carbon atoms, aromatic hydrocarbon group, or saturated hydrocarbon group with 1 to 8 carbon atoms and having an aromatic hydrocarbon group; n is 0 or an integer of 1 to 3; X is a hydroxyphenyl group expressed by general formula (2) below; and A is a tetravalent carbon atom group or tetravalent saturated hydrocarbon group with 2 or more carbon atoms; wherein when A is a tetravalent saturated hydrocarbon group with 2 or more carbon atoms, two carbon atoms in the A group are each bonded to two phenyl groups); (in the formula, R 2 is an alkyl group with 1 to 8 carbon atoms, alkoxyl group with 1 to 8 carbon atoms, aromatic hydrocarbon group, or saturated hydrocarbon group with 1 to 8 carbon atoms and having an aromatic hydrocarbon group; a is an integer of 1 to 3; and b is 0 or an integer of 1 to 4; wherein when 1≦a+b≦5 and b is 2 or greater, R 2 s may be either the same or different).
