Compositions and methods for preventing radical polymerization of ethylenically unsaturated aliphatic monomers

摘要

The invention concerns a composition for inhibiting radical polymerisation of ethylenically unsaturated aliphatic monomers characterised in that it comprises at least a diphenylamine derivative of general formula (I) wherein: A and B represent the radical of a cycle forming all or part of a carbocyclic, aromatic, monocyclic or polycyclic system; R1 and R2, identical or different, represent a hydrogen atom or one or several substituents; and n + m not less than 1: n and m representing the number of substituents on the cycle.
