  It is an object of the invention to provide a process of inhibiting polymerization of isocyanate group-containing, ethylenically unsaturated carboxylate compounds, and a process for producing isocyanate group-containing, ethylenically unsaturated carboxylate compounds which involves the polymerization inhibition process. The process of inhibiting polymerization of isocyanate group-containing, ethylenically unsaturated carboxylate compounds of the invention includes controlling the oxygen gas (O2) concentration in a liquid phase containing an isocyanate group-containing, ethylenically unsaturated carboxylate compound to not less than 0.5 mg/L. In a preferred embodiment, a gas containing oxygen gas (O2) is introduced to the liquid phase. In another preferred embodiment, the oxygen gas (O2) concentration in the liquid phase is measured with an electrode that is immersed in the liquid phase.
