Epoxy ester resins (EPR) were prepared by reaction between Diglycidyl ether of resacetophenone (DGE-RAP) and various acrylic acid derivatives. All the epoxy ester resins were characterized by elemental analysis, viscosity, unsaturation and IR spectral studies. Curing characteristic of DGE-RAP and their mixture with vinyl monomers was monitored by differenctial scanning calorimetry (DSC). Thermal stability of cured materials was determined by thermogravimetric analysis (TGA). The glass fibre reinforced composite of these resins and cryolite were prepared and characterized by chemical and mechanicalproperties.
