    Abstract: The invention relates to a method for producing Heonon(meth)acrylate via the transesterification of alkyl(meth)acrylate with Heonon, comprising the following steps: (i) permitting alkyl(meth)acrylate to react with Heonon in the presence of a catalyst containing titanium (IV) or zirconium (IV) and a stabiliser in the presence of an entrainer, forming an azeotrope with the alcohol bonded in the alkyl(meth)alcylate; (ii) continuous distilling off of the azeotrope from the entrainer and alcohol, wherein steps (i) and (ii) are carried out simultaneously, until heonon is substantially completely converted; (iii) adding water to the product mixture obtained in steps (i) and (ii) and containing heonon(meth)acrylate, and separating the hydrolysate from the catalyst containing titanium (IV) or zirconium (IV) by means of filtration; (iv) distilling off of non-converted alkyl(meth)acrylate and entrainer from the product mixture; (v) distilling off of water from the product mixture, wherein step (iv) can also be carried out before step (iii), and the steps (iv) and (v) can also be carried out in a distillation step, characterised in that the steps (i) and (ii) are carried out in the presence of an inorganic or organic acid.
