General description
Triethylene glycol dimethacrylate is used as a cross-linking agent in the synthesis of poly (methacrylic acid-g-ethylene glycol ) hydrogels which shows large changes in swelling due to changes in pH, temperature and solvent composition. They are also used as a divinylic methacrylic monomer which are widely used to form copolymers with divinylbenzene (DVB) and glycidyl methacrylate (GMA) or hydroxyethyl methacrylate (HEMA) comonomers.
Application
- Used as a diluent comonomer in dimethacrylate based dental composites.
- Used as a branching agent in the atom transfer radical polymerization (ATRP) of styrene.
Features and Benefits
Lower viscosity compared to other dimethacrylate monomers enabling higher amounts of filler to be incorporated in dental composites. Non-toxic and can be rapidly polymerized in the presence of oxygen and water.
