 Ethylene glycol dimethylacrylate (EGDMA) is a diester formed by condensation of two equivalents of methacrylic acid and one equivalent of ethylene glycol.
EGDMA can be used in free radical copolymer crosslinking reactions. When used with methyl methacrylate, it leads to gel point at relatively low concentrations because of the nearly equivalent reactivities of all the double bonds involved.

Ethylene dimethacrylate Usage And Synthesis
Description    It is mainly applied in the field of organic synthesis, such as a crosslinking agent for fabricating resin, resin processing, fabricating adhesives and coatings, rubber resin modifier, anaerobic adhesive, and plastic paste. Specifically, this chemical can be used as the raw material to prepare a copolymer that has been demonstrated to act as a biocompatible interface between glucose biosensors and tissue in the rat.1 Moreover, this compound may be involved in the preparation of poly(2-vinyl-4,4-dimethylazlactone-co-acrylamide-co-ethylene dimethacrylate) for designing the porous support for high throughput reactors.2 In addition, the bulk polymerization of this chemical and glycidyl methacrylate results in the formation of porous monolith as a stationary phase in dye-affinity chromatography.3
