Abstract: The present invention provides a (meth)acrylate containing a heterocyclic ring, which is a structure necessary for achieving physical properties required in many fields, and a hydrophilic group in the same monomer molecule and further provides a process for producing the same from industrially easily-available starting materials by industrially feasible reactions. A (meth)acryloyloxytetrahydrofuran having a structure represented by the following general formula (1): wherein R1 and R2 each is a hydrogen atom or a (meth)acryloyl group represented by the following general formula (2) and at least one of R1 and R2 is a (meth)acryloyl group represented by the general formula (2).

Abstract: An object of the present invention is to provide a process for purifying 2-methyladamantan-2-yl(meth)acrylate with high separation efficiency and an industrially advantageous preparation process of 2-methyladamantan-2-yl(meth)acrylate. The present invention pertains to a preparation process of 2-methyladamantan-2-yl(meth)acrylate which comprises reacting 2-methyleneadamantane and (meth)acrylic acid by an acid catalyst to obtain a reaction mixture, and then separating 2-methyleneadamantane from the reaction mixture to obtain 2-methyladamantan-2-yl(meth)acrylate, wherein the reaction mixture is distilled in the presence of an organic compound having a boiling point, under atmospheric pressure, of 150° C. or greater but not greater than 260° C.
