The present invention discloses an adamantyl esternmonomer composition characterized by containing at least annadamantyl ester monomer having at least one polymerizablenunsaturated bond in the molecule, and a compound representednby the following general formula (1):n n(in the formula, R 1 is an alkyl group of 1 to 5 carbon atoms,nR 2 is an alkyl group of 1 to 5 carbon atoms, R 3 is a hydrogennatom or an alkyl group of 1 to 5 carbon atoms, and R 4 is anhydrogen atom or a methyl group). The composition has highnstorage stability and, by subjecting it to distillation, annadamantyl ester monomer of high purity can be obtained easily. |
