Abstract
A polynuclear polyphenol compound is constituted by, as a main skeleton, a 4,4′-methylene bis phenol structure where tris phenol skeletons of tris phenyl methane type are mutually bonded by methylene groups, wherein the reactivity of two hydroxyl groups bonded to the central skeleton of 4,4′-methylene bis phenol is significantly different from the reactivity of hydroxyl groups respectively bonded to the four phenyl groups of the two diphenyl methyl substituted groups.
