The present invention provides a method for preventing polymerization, and a polymerizable monomer composition favorably used therefor that includes a (meth)acryloyl group-containing isocyanate compound and a specific polymerization inhibitor. The polymerizable monomer composition includes a (meth)acryloyl group-containing isocyanate compound and a stable free radical compound. The invention effectively prevents the polymerization of the (meth)acryloyl group-containing isocyanate compound and the occurrence of polymers due to the polymerization. Furthermore, the use of a stable free radical compound which has a vapor pressure approximate to that of the (meth)acryloyl group-containing isocyanate compound can effectively prevent polymerization in a vapor phase and a condensation phase of distillation facility.
La présente invention concerne un procédé pour prévenir la polymérisation, et une composition de monomère polymérisable utilisée favorablement pour cela qui comprend un composé isocyanate contenant un groupe (méth)acryloyl et un inhibiteur spécifique de la polymérisation. La composition de monomère polymérisable comprend un composé isocyanate contenant un groupe (méth)acryloyl et un composé radical libre stable. L'invention prévient de manière efficace la polymérisation du composé isocyanate contenant un groupe (méth)acryloyl et l'apparition de polymères dus à la polymérisation. De plus, l'utilisation d'un composé radical libre stable qui a une tension de vapeur proche de celle du composé isocyanate contenant un groupe (méth)acryloyl peut prévenir de manière efficace la polymérisation dans une phase vapeur et une phase de condensation d'une installation de distillation.
