Descrizione generale

Diphenyl(2,4,6-trimethylbenzoyl)phosphine oxide (TPO) is a monoacylphosphine oxide based photoinitiator that can be incorporated in a variety of polymeric matrixes for efficient curing and color stability of the resin.

Applicazioni

TPO can be used in the photo-crosslinking of PMMA composite, which can further be used as a gate insulator in organic thin film transistors (OTFTs). It can also be used in the formation of UV curable urethane-acrylate coatings. It may also be used in the photoinduced reaction for the formation of organophosphine compounds, which potentially find their usage as ligands with metal catalysts and reagents.

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.
