Abstract
An alicyclic (meth)allyl ester monomer obtained by a specific production process. An alicyclic (meth)allyl ester compound for plastic lenses, which can be obtained by a simple and easy production process and which can endure a long-term storage, is produced using the monomer, and a plastic lens is obtained using the compound.
Claims14
A process for producing an alicyclic (meth)allyl ester monomer, comprising reacting a polyvalent alkyl ester of a polybasic acid having an alicyclic structure with an allyl alcohol and/or a methallyl alcohol in the presence of a transesterification catalyst.
