Abstract: A polymerizable monomer, which is represented by the following general formula (1): in the general formula (1), X represents a divalent group, 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 hydrocarbon group having a main chain with a number of atoms within a range of from 2 to 60 and having a valence selected from divalence to tetravalence, and may be identical to or different from each other, R1 and R2 each represent a hydrogen atom or a methyl group, and m1, m2, n1, and n2 each represent an integer selected from a range of from 1 to 3; and a method of producing the polymerizable monomer, a curable composition and a resin member each using the polymerizable monomer.

Abstract: Provided are: a polymerizable monomer excellent in mechanical strength of its cured product and excellent also in handling property with low viscosity even under a room temperature environment, specifically, 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, 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, q represents 0 or 1, and m1 and m2 each represent 1 or 2; and a method of producing the polymerizable monomer, a curable composition and a resin member each using the polymerizable monomer.
