Opis ogólny

Methyl methacrylate is an organic compound derived from methacrylic acid, which belongs to the class of acrylic acids. It is a highly reactive monomer and is commonly used in the production of polymers, specifically poly(methyl methacrylate) (PMMA). It is also used to synthesize various poly(methyl methacrylate) (PMMA) materials, which are transparent, hard, and durable. These materials have a wide range of applications, including optical lenses, optoelectronic devices, automotive parts, and medical devices. It is also a good solvent for several polymers and provides high adhesive strength.

Zastosowanie

Methyl methacrylate can be used as a monomer to prepare:
  • Lanthanide-complex grafted poly(methyl methacrylate-co-maleic anhydride) copolymer. These luminescent polymers exhibit high thermal stability and can be used as luminous layers for optoelectronic devices.
  • Poly (methyl methacrylate) (PMMA), is a common material used in the production of lenses for concentrating photovoltaic (CPV) modules.
  • Polymethyl methacrylate, methyl methacrylate crosspolymer, and methyl methacrylate/glycol dimethacrylate crosspolymers. These polymers are used in cosmetic surgery, dentistry, and joint replacement.
  • Poly (methyl methacrylate) (PMMA)-based personalized medical devices.
Methyl methacrylate can be used as a monomer to prepare:
  • Interpenetrating methyl methacrylate-based polymeric networks with enhanced thermal and mechanical properties.
  • Poly(methyl methacrylate-co-hydroxyethyl methacrylate) (PMMA-co-PHEMA) copolymers by emulsion copolymerization. These copolymers form thermooxidatively stable and ductile films.
  • Poly(methyl methacrylate) nanoparticles through differential microemulsion polymerization.

Reversible Addition Fragmentation Chain Transfer (RAFT) Polymerization

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.

Continuous Flow Manufacturing for Monomer Synthesis

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.
