Abstract

Method for inhibiting the polymerization of acrylic acid characterized in that in its realization it comprises constituting a combination of said acrylic acid with an amount equal to at least 1 ppm of an aromatic nitrous compound chosen from the class of N-nitroso-arylamines and of the compounds that contain the group NO linked directly to a carbon atom of the aromatic nucleus.
