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.

Application

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).
