TThe invention provides a composition of matter and a method of its use in preventing unwanted polymerization reactions. The composition comprises an inhibitor and a retarder. The inhibitor is highly effective. The retarder is reliable under extreme and emergency situations. The inhibitor can be an alkylhydroxylamine. The retarder can be a 7-cyano-quinone methide. The combination of the inhibitor and retarder has been found to be far more effective than expected. L'invention porte sur une composition de matière et sur un procédé pour l'utiliser afin d'empêcher des réactions de polymérisation non souhaitées. La composition comprend un inhibiteur et un retardateur. L'inhibiteur est hautement efficace. Le retardateur est fiable dans des situations extrêmes et d'urgence. L'inhibiteur peut être une alkylhydroxylamine. Le retardateur peut être un 7-cyano-quinone méthide. Il a été constaté que la combinaison de l'inhibiteur et du retardateur était bien plus efficace que ce à quoi l'on s'attendait.
