PEGDMA dimethacrylate

In 1959, Miller (1959a,fc) reported that radiation polymerization of a plasticized PVC containing a divinyl monomer could be used to crosslink PVC effectively without seriously affecting thermal stability. Three monomers were used poly(ethylene glycol dimethacrylate) (PEGDMA), ethylene glycol... 

Commonly used chain formers are methacrylamide (MAM), hydroxymethacry-lamide (HMAM), N-vinyl pyrrolidone (NVP), and methoxy poly(ethylene glycol) monomethacrylate (MPEGMA). Sometimes two monomers may be used in combination (e.g., MAM and NVP, or MPEGMA and HMAM). The cross-linkers commonly used are methylene bisacrylamide (MBAM) and poly(ethylene glycol) dimethacrylate (PEGDMA). The free radical initiator used most often is ammonium persulfate (APS) with tetramethylethylene diamine (TEMED) used as a catalyst. 

Also in the field of hydrogels, (meth)acrylates play an important role. Since there is quite a number of hydrophilic methacrylate-based monomers available, radical copolymerization with an appropriate crosslinking monomer leads to network formation. The most widely used monomers are 2-hydroxyethyl methacrylate HEMA, 2-aminoethyl methacrylate and the alkyl derivatives, amethacrylamid and the alkyl derivatives, ethyleneglycol dimethacrylate EGDMA, and polyethyleneglycol dimethacrylate PEGDMA. 

Even with the successes of these methods, synthesis of selective membrane skins with minimal (< 50 nm) thicknesses is still difficult. Balachandra et at [47] described the use of room-temperature atom transfer radical polymerization (ATRP) from a substrate to synthesize two types of ultrathin ( 50 nm) polymer skins crosslinked poly(ethylene glycol dimethacrylate) (PEGDMA) and linear poly(2-hydroxyethyl methacrylate) (PHEMA).
