Tetraethylene glycol dimethacrylate Usage And Synthesis

Description	Tetraethylene glycol dimethacrylate is a crosslinking agent of acrylic resins, employed to optimize the dilution of high-viscosity monomers and to link together the macromolecules costituting the polymer, to make their three-dimentional structure more rigid. Occupational dermatitis was reported in a dental technician.
Chemical Properties	Water-white to pale-straw liquid. Insoluble in water; soluble in styrene, many esters, and aromatics; limited solubility in aliphatic hydrocarbons. Combustible.
Uses	methacrylate present in adhesives; in polyethyleneglycol dimethacrylate in Loctite anaerobic sealants.
Uses	High purity PEG dimethacrylates are commonly used in PEG-based hydrogels and crosslinking hydrophilic polymers.
Uses	Plasticizer.
Hazard	Irritant to skin and eyes.
