| 摘要 |
<p>The present invention discloses an adamantyl ester monomer composition characterized by containing at least an adamantyl ester monomer having at least one polymerizable unsaturated bond in the molecule, and a compound represented by the following general formula (1): <CHEM> (in the formula, R<1> is an alkyl group of 1 to 5 carbon atoms, R<2> is an alkyl group of 1 to 5 carbon atoms, R<3> is a hydrogen atom or an alkyl group of 1 to 5 carbon atoms, and R<4> is a hydrogen atom or a methyl group). The composition has high storage stability and, by subjecting it to distillation, an adamantyl ester monomer of high purity can be obtained easily.</p> |
