NEW MATERIAL:The tetraacrylate of formula I. USE:Useful as a crosslinking agent, cure-accelerator and modifier for a resin composition curable by radical reaction. PREPARATION:The compound of formula I can be produced by reacting vinyl- cyclohexene diepoxide with 2-hydroxyethyl acrylate, and esterifying the resultant compound of formula II with acrylic acid or its derivative. The above reaction is carried out in the presence of sulfuric acid or p-toluenesulfonic acid as the catalyst. The polymerization inhibitor used in the above reaction is preferably the one removable easily by washing, e.g. hydroquinone, hydroquinone monomethyl ether, etc. Water produced by the esterification reaction is removed from the system by the use of an azeotropic solvent such as benzene, toluene, etc.
