Ethylene dimethacrylate Chemical Properties,Usage,Production

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

Description

The crosslinking agent of acrylic resins, ethyleneglycol dimethacrylate (EGDMA), is employed to optimize the dilution of high-viscosity monomers and to link together the macromolecules costituting the polymer. It caused contact dermatitis in dental technicians and dental assistants. A case was also reported in a car rear-view mirror manufacturer.

Uses

Ethylene glycol dimethacrylate is used as a functional monomer for polymers and as a cross linking agent between the molecular chains of polymers and elastomers. It is also used in free radical copolymer cross linking reactions. It acts as an intermediate in the production of hydroxyapatite and poly methyl methacrylate composites. It is also used in dentaI composites, sealants, prostheses, adhesives, artificiaI nails, printing inks, etc.

Definition

ChEBI: Ethylene glycol dimethacrylate is the enoate ester that is the 1,2-bis(methacryloyl) derivative of ethylene glycol. It has a role as a cross-linking reagent, a polymerisation monomer and an allergen. It is functionally related to an ethylene glycol and a methacrylic acid.

General Description

Ethylene glycol dimethylacrylate (EGDMA) is a diester formed by condensation of two equivalents of methacrylic acid and one equivalent of ethylene glycol.
