PROBLEM TO BE SOLVED: To provide a method for producing a polycarbonate diol diacrylate compound from polycarbonate diol and an acrylic ester compound without using a protonic acid and a metal component.SOLUTION: In the method for producing a polycarbonate diol diacrylate compound, polycarbonate diol represented by formula (I) is reacted with an acrylic ester compound represented by formula (II) in the presence of lipase. In formula (I), each Ris the same or different and a divalent group composed of one or more straight chain, branched chain, or cyclic alkylene groups, wherein the divalent group may have a substituent and/or one or more non-terminal carbon atoms substituted with a divalent aromatic group, a divalent heterocyclic group, an oxygen atom, or a sulfur atom, or is a divalent group of a crosslinking carbocyclic ring; and n represents an average degree of polymerization and is a number of 1-50. In formula (II), Ris a hydrogen atom or a 1-4C straight chain or branched chain alkyl group; and Ris a 1-12C straight chain, branched chain or cyclic alkyl group, a 7-10C aralkyl group or a 6-10C aryl group. |
