Preparation method of (methyl)acrylate with bridged ring structure

The invention relates to a preparation method of (methyl)acrylate with a bridged ring structure. The (methyl)acrylate is synthesized through three-step reaction comprising the following steps: firstly, carrying out direct addition on saturated fatty acid and bridged ring olefin or a derivative thereof; rectifying and purifying, thus removing a byproduct generated by self-polymerization of the bridged ring olefin; then carrying out hydrolysis to obtain corresponding bridged ring alcohol or a derivative thereof; finally, carrying out ester exchange reaction between the (methyl)acrylate and the bridged ring alcohol or the derivative thereof to obtain the (methyl)acrylate with the bridged ring structure. The preparation method provided by the invention is simple, and the steps are easy to operate; a target product is obtained through the three-step reaction and the yield is high; the disadvantages of a rectification process of a direct esterification technology that the requirements are high and the yield is low are overcome; the content of a residual cycloolefin monomer in the product is low; when the preparation method is applied to resin synthesis, the disadvantages that resin becomes yellow and the viscosity is increased can be remarkably relieved.
