The invention concerns novel tetraglycidates of the formula
wherein R1 and R2 are independently hydrogen, alkyl of 1 to 8 carbon atoms, perfluoroalkyl, and cycloalkylidene of 5 to 7 carbon atoms. Epoxy resin systems of said epoxy resins and a polyamine curing agent exhibiting good tensile properties and moisture sensitivity. The epoxy resin system may include a co-epoxide and is used together with a fiber reinforcement for producing prepregs systems.
