| Application: | PEGMA can beused as a monomer to synthesize:• Degradable microspheres using asuspension polymerization process. The amphiphilic nature of PEGMA allows performingthe polymerization by direct oil in the water suspension process. • Polymeric chelating beads for the effectiveremoval of heavy metals from aqueous solutions. It can also be used to synthesize micro or nanoparticles-basedchitos |
| General description: | Polyethylene glycol (PEG) is a suitable material for biological applications since it does not trigger an immune response. It can by synthesized by anionic ring opening polymerization of ethylene oxide with a range of end groups (such as methacrylate: PEGMA) attached. PEG is a hydrophilic polymer that can form hydrogels when cross linked into networks. Acrylate and methacrylate chain ends undergo chain polymerization to from PEGMA hydrogels. |
