General description

Methyl methacrylate is an industrially important monomer and building block for acrylic-based polymers. It is a good solvent for several polymers and provides high adhesive strength.

Application

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.
  • 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) nanoparticles through differential microemulsion polymerization.
