To investigate the extent of these deviations, copolymer emulsions of VA with butyl acrylate (BA), 2-ethyl hexyl acrylate
(2-EHA), and VeoVa were prepared under emulsion polymerization conditions.
Examples of pairs include polystyrene and poly(2-ethyl hexyl acrylate
), polystyrene and poly(butyl acrylate), poly(ethyl acrylate) and poly(ethyl methacrylate), or polystyrene and poly(hexyl methacrylate).
[19, 20] have shown that poly(2-ethyl hexyl acrylate
) (CTPEHA) liquid rubber with terminal carboxyl groups ([M.sub.n] = 3600, f = 1.9) can be used as an effective impact modifier for epoxy resin cured with an ambient temperature hardeners.
Arkema will open a new 2-ethyl hexyl acrylate
production unit at its Carling site in France to keep up with the strong growth of the acrylic esters market.
