Glycidyl methacrylate (GMA) is an ester of methacrylic acid and glycidol. Containing both an epoxide and an acrylate groups, the molecule is bifunctional . It is a common monomer used in the production of epoxy resins.
Bis-GMA (bisphenol A-glycidyl methacrylate) is a resin commonly used in dental composite, dental sealants. [1] [2] and dental cement. It is the diester derived from methacrylic acid and the bisphenol A diglycidyl ether. Bearing two polymerizable groups, it is prone to form a crosslinked polymer that is used in dental restorations.

Glycidol is prepared by the epoxidation of allyl alcohol.A typical catalyst is tungstic acid, and a typical O-atom source is aqueous peroxyacetic acid. [8]Some useful products derived from glycidol are 2,3-epoxypropyloxy chloroformate (from phosgene) and glycidyl urethanes (by addition of isocyanates: [8]

Two examples of such commonly used monomers include bisphenol A-glycidyl methacrylate (BISMA) and urethane dimethacrylate (UDMA), together with tri-ethylene glycol dimethacrylate (TEGMA). TEGMA is a comonomer which can be used to control viscosity, as Bis GMA is a large molecule with high viscosity, for easier clinical handling. [ 12 ]
