Polycyclic polyphenolic resin and method for producing polycyclic polyphenolic resin

Abstract

A polycyclic polyphenolic resin having a repeating unit derived from at least one monomer selected from the group consisting of an aromatic hydroxy compound represented by the following formulae (1A) and (1B), wherein the repeating units are linked to each other by a direct bond between aromatic rings, wherein X represents an oxygen atom, a sulfur atom, a single bond or non-crosslinked state, and Y represents a 2n-valent group having 1 to 60 carbon atoms or a single bond, wherein when X is non-crosslinked state, Y represents the 2n-valent group; A represents a benzene ring or a fused ring; each R0 is independently an alkyl group having 1 to 40 carbon atoms and optionally having a substituent, an aryl group having 6 to 40 carbon atoms and optionally having a substituent, an alkenyl group having 2 to 40 carbon atoms and optionally having a substituent, an alkynyl group having 2 to 40 carbon atoms, an alkoxy group having 1 to 40 carbon atoms and optionally having a substituent, a halogen atom, a thiol group, or a hydroxy group, wherein at least one R0 is a hydroxy group; and each m is independently an integer of 1 to 9; and n is an integer of 1 to 4; and each p is independently an integer of 0 to 3.
