Description

General description

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

Application

Ethylene glycol dimethacrylate can be used as a cross-linker in thepreparation of:

• A terpolymer system, poly(acrylonitrile-co-Ethyleneglycol dimethacrylate-co-vinylbenzyl chloride), which is applicable as a sorbentin pharmaceuticals adsorption.
• PVA (polyvinyl alcohol) based hydrogel by free-radicalcopolymerization. These PVA polymer networks can be used as drug deliverysystems.

It can also be used asa monomer in the preparation of swellable and non-swellable poly(ethyleneglycol dimethacrylate/acrylic acid) copolymer microspheres through suspensionpolymerization.
