Descripción general

Methacrylic acid (MAA) is an organic compound, colorless, viscous liquid. It is a monofunctional methacrylayte monomer. It is soluble in warm water and miscible in most organic solvents. MAA is used as a starting material for the production of its esters, especially methyl methacrylate and poly methyl methacrylate (PMMA).

Aplicación

MAA is used to synthesize poly(methacrylic acid)-g-poly(ε-caprolactone) copolymers, polymeric blends with PMMA and hydroxyethyl methacrylate (HEMA)-MAA hydrogels.

RAFT (Reversible Addition Fragmentation chain Transfer) polymerization is a reversible deactivation radical polymerization (RDRP) and one of the more versatile methods for providing living characteristics to radical polymerization.

The manufacture of monomers for use in ophthalmic applications is driven by the need for higher purity, improved reliability of manufacturing supply, but ultimately by the need for the increased comfort, convenience, and safety of contact lens wearers. Daily wear contact lenses have the potential to fill this need for many customers; however, their widespread use is constrained by higher costs compared to weekly- or monthly-based lenses. New approaches that improve cost structure and result in higher quality raw materials are needed to help make contact lenses more affordable and accelerate growth of the contact lens market.
