Ethylene glycol dimethacrylate

Ethylene glycol dimethylacrylate is a diester formed by condensation of two equivalents of methacrylic acid and one equivalent of ethylene glycol. It has the structural formula: CH2=C(CH3)-CO-O-CH2-CH2-O-CO-C(CH3)=CH2. It can be used in radical copolymer crosslinking reactions. When used with methlyl methacrylate, it leads to gel point at relatively low concentrations because of the nearly equivalent reactivities of all the double bonds involved.
