The present invention relates to a process for the production of (meth) acrylates, the (meth) acrylates produced by this process, and their use for the production of high molecular weight homopolymers or copolymers. It is produced by reacting a (meth) acrylate of formula (II) with an alcohol of formula (III) in the presence of a catalyst and a phenolic polymerization inhibitor, wherein the reaction is oxygen or oxygen containing The gas mixture is measured at a specific total oxygen input of 1.0 L / kg or less (the above is measured in liters of oxygen per kilogram of (meth) acrylate of formula (I), where the volume of oxygen introduced is at a temperature of 25 ° C. And (meth) acrylate of formula (I): CH 2 ═C (R 1 ) CO—O—R 2 (I), which is started by charging into the reaction mixture at a pressure of 101325 Pa and And its use for the production of high molecular weight polymers.
