General description

2-Ethylhexyl acrylate can undergo free radical solution polymerization to yield its polymer. It can form a series of copolymers via atom transfer radical copolymerization. A study reports the emulsion terpolymerization of the product with styrene, methacrylic acid.
2-ethylhexyl acrylate (EHA) is one of the constituents of acrylic polymeric latex. It can undergo free-radical solution polymerization. EHA is known to undergo free radical emulsion co- polymerization with methyl methacrylate (MMA) to form pressure-sensitive adhesives. It may also form copolymers with acrylonitrile and acrylamide.
