摘要

PROBLEM TO BE SOLVED: To produce a polycyclic (meth)acrylate having a reduced content of impurities by an industrially feasible method.;SOLUTION: In the method for producing the polycyclic (meth)acrylate represented by formula (2) and/or formula (3) (wherein R1 and R2 are each independently hydrogen or a 1-12C alkyl group; n is 0 or 1; and R is hydrogen or a methyl group) by the addition reaction of a lactone compound represented by formula (1) (wherein R1, R2, and n are the same as defined above) with (meth)acrylic acid, water and sulfuric acid are allowed to be present in the reaction system in an amount of water of ≥5 wt.% based on 100 wt.% sum of the water and sulfuric acid and an organic solvent immiscible with the water and sulfuric acid is used.;COPYRIGHT: (C)2006,JPO&NCIPI
