Descrição

Descrição geral

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. [1] 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.[2]

Aplicação

• Used as a diluent comonomer in dimethacrylate based dental composites.[3]
• Used as a branching agent in the atom transfer radical polymerization (ATRP) of styrene.[4]

Características e benefícios

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. [3]
