General description

2-(4-Benzoyl-3-hydroxyphenoxy)ethyl acrylate is a derivative of oxybenzone that is widely used as a UV-blocking agent in the fabrication of contact lenses. It contains both a vinyl group and an aromatic benzoyl group which makes it useful in polymerization and crosslinking reactions. This acrylate monomer is commonly used as a building block in the synthesis of polymers utilized in various coatings, adhesives, and dental fillings. Due to its unique structure, it can exhibit desirable properties such as high reactivity, good adhesion to a variety of substrates, and resistance to UV degradation.

Application

2-(4-Benzoyl-3-hydroxyphenoxy)ethylacrylate can be used as a monomer to synthesize fluorine-silicone acrylic resinto improve the UV resistance of the resin and make it more durable andlong-lasting.

Chemical investigations of ultraviolet-absorbing hydrogel material for soft intraocular lenses.

T V Chirila et al.

Journal of cataract and refractive surgery, 15(5), 504-509 (1989-09-01)

A poly(2-hydroxyethyl methacrylate) hydrogel material exhibiting ultraviolet-absorbing properties was synthesized by simultaneous polymerization, crosslinking, and covalent bonding of an available polymerizable absorber. The two-stage leaching experiments carried out by aqueous extraction and the analysis of the concentrated extracts by high

Further studies on ultraviolet-absorbing hydrogels for intraocular lenses: relationship between concentration of a polymerizable benzophenone, absorption, and extractability.

T V Chirila et al.

Journal of cataract and refractive surgery, 17(5), 596-603 (1991-09-01)

A tendency to reduce the use of benzophenone absorbers is currently evident in the manufacture of the UV-absorbing IOLs, mainly because the cutoff wavelengths are inferior to those provided by benzotriazoles. In principle, by incorporating large amounts of benzophenones it
