Polymerizable monomer, method of producing polymerizable monomer, curable composition and resin member

A polymerizable monomer, which is represented by the following general formula (1′):

• in the general formula (1′), Ar1 and Ar2 each represent an aromatic group having a valence selected from divalence to tetravalence, and may be identical to or different from each other, L1 and L2 each represent a divalent hydrocarbon group having a main chain with a number of atoms within a range of from 2 to 10 and containing at least one hydroxy group, and may be identical to or different from each other, R1 and R2 each represent hydrogen or a methyl group, and m1 and m2 each represent 1 or 2.

A method of producing a polymerizable monomer, the polymerizable monomer comprising two or more kinds of structural isomers selected from the group consisting of compounds represented by the following general formulae (6′) to (8′), the method comprising at least a reaction step of allowing a compound represented by the following general formula (4′) and a compound represented by the following general formula (5) to react with each other:

• in the general formulae (4′), (5), and (6′) to (8′), Ar1 and Ar2 each represent a divalent aromatic group, and may be identical to or different from each other, L5 represents a divalent hydrocarbon group having a main chain with a number of atoms of from 1 to 7, and p represents 0 or 1.
