    Abstract: Dihydrodicyclopentadienyl acrylatr (I), useful in production of impact-proof (co)polymers e.g. with acrylonitrile or styrene, is prepared by reacting dicyclopentadiene with 1.1-5 times molar excess acrylic acid, containing 0.05-0.3 wt.% polymerisation inhibitor, in the presence of acid catalysts at 40-110 degrees C extracting the mixture with water and separating (I) from aqs. layer. Reaction and working up take place in absence of metal salts, in steel vessels with inner surface completely enamelled coated with plastic or lined with ceramic so that reaction mixture does not contact the metal, and so that emulsifying is completely prevented.
