Rate coefficients for the reactions of NO3 with n-butyl methacrylate (k(1)), iso-butyl methacrylate (k(2)) and tert-butyl methacrylate (k(3)) have been determined at 298 K and atmospheric pressure using the relative rate method. The following rate coefficients (x 10(-15) cm(3) molecule(-1) s(-1)) were obtained for the first time: k(1) = (5.5 +/- 2.6), k(2) = (5.8 +/- 2.8) and k(3) = (5.6 +/- 2.5). The NO3 reactions of these compounds could contribute to the removal of NOx and as NOy reservoirs. The potential importance for the tropospheric nitrogen budget of these reactions is discussed and atmospheric lifetimes for the butyl esters are calculated. (C) 2016 Published by Elsevier B.V.
