Leírás

Általános leírás

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.

Alkalmazás

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-basedchitosan /PEGMA composite by Michael addition reaction. The PEGMA graftingimproves the solubility of chitosan in aqueous media. These particles can beused as carriers in the ophthalmic drug delivery system.
