METHOD FOR PRODUCING POLYFUNCTIONAL (METH)ACRYLATE

WIPO Patent Application WO/2017/033611

A1

[Problem] The present invention addresses the problem of producing a polyfunctional (meth)acrylate with high yield by carrying out a transesterification reaction between a specific monofunctional (meth)acrylate and a polyhydric alcohol. [Solution] A method for producing a polyfunctional (meth)acrylate by carrying out a transesterification reaction between at least one monofunctional (meth)acrylate selected from the group consisting of methyl (meth)acrylate, ethyl (meth)acrylate, i-butyl (meth)acrylate and 2-dimethylaminoethyl (meth)acrylate and a polyhydric alcohol, said method being characterized in that a catalyst A and a catalyst B as mentioned below are used together. The catalyst A: at least one compound selected from the group consisting of a cyclic tertiary amine having an azabicyclo structure or a salt or complex thereof, an amidine or a salt or complex thereof, and a compound having a pyridine ring or a salt or complex thereof. The catalyst B: at least one compound selected from the group consisting of zinc-containing compounds.
