Title (EN) USE OF POLYMERIZATION INHIBITOR COMPOSITIONS
(FR) UTILISATION DE COMPOSITIONS INHIBITRICES DE POLYMÉRISATION
Abstract:
(EN) The present invention relates to the use of at least two phenol derivatives jointly with at least one ancillary polymerization inhibitor which is different from these two phenol derivatives and particularly is selected from phenol derivatives, amine derivatives, thiazine derivatives, nitroso compounds, N-oxyl derivatives, metal salts, quinone derivatives, and mixtures thereof, to inhibit the polymerization of ethylenically unsaturated monomers comprising at least one heteroatom, it being also possible for a dispersant to be incorporated. The present invention also relates to a corresponding polymerization-inhibiting composition and to the corresponding process for preparing ethylenically unsaturated monomers comprising at least one heteroatom, and particularly acrylic monomers.
(FR) L'invention concerne l'utilisation d'au moins deux dérivés de phénol avec au moins un inhibiteur de polymérisation auxiliaire qui est différent de ces deux dérivés de phénol, et est en particulier sélectionné à partir de dérivés de phénol, dérivés d'amine, dérivés de thiazine, composés nitroso, dérivés N-oxyle, sels métalliques, dérivés de quinone, et leurs mélanges, pour inhiber la polymérisation de monomères à insaturation éthylénique, comprenant au moins un hétéroatome, un dispersant pouvant également être incorporé. La présente invention concerne également une composition inhibitrice de polymérisation correspondante et le procédé correspondant de préparation de monomères à insaturation éthylénique comprenant au moins un hétéroatome, et en particulier des monomères acryliques.
