General description

Butyl acrylate is a clear colorless liquid. It is a vinyl monomer. It undergoes radical copolymerization with benzoxazine containing a vinyl group to afford copolymers. Heck coupling reactions of aryl bromides with n-butyl acrylate mediated by phosphine-imidazolium salt has been reported. Copolymerization of styrene and n-butyl acrylate by ATRP catalyzed by CuBr/4,4′-di(5-nonyl)-2,2′-bipyridine has been described.


Butyl acrylate is used to prepare:
  • Poly(butyl acrylate) particles.
  • Poly(butyl acrylate-b-acrylic acid) block copolymer.
  • Amphiphilic charged diblock copolymers poly(butyl acrylate)-b-poly(acrylic acid).
  • Poly(n-butyl acrylate), via atom transfer radical polymerization (ATRP) of n-butyl acrylate in the presence of CuIBr/4,4′-di(5-nonyl)-2,2′-bipyridine (catalyst).

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.
