Abstract
Methacrylate esters of alcohols having an ether linkage and/or an alicyclic ring can be obtained with no trouble of coloration or polymer formation during the production and for the product. An alcohol having an ether linkage and/or an alicyclic ring is treated with an alkaline substance, and the treated alcohol is caused to react with methyl methacrylate for a transesterification reaction in the presence of an alkaline substance.
