The present invention relates to a method of enhancing the flame retardancy of nitrogenous phosphorus and/or sulfonate flame retardants, the enhanced ( or activated) nitrogenous phosphorus and/or sulfonate flame retardants and their applications. The activated flame retardants are activated with either a char forming catalyst, a phase transfer catalyst or both.
L'invention se rapporte à un procédé permettant de renforcer les propriétés ignifuges d'ignifugeants comprenant du phosphate azoté et/ou du sulfonate azoté, à des ignifugeants renforcés (ou activés) qui contiennent du phosphate azoté et/ou du sulfonate azoté, ainsi qu'à leurs utilisations. Lesdits ignifugeants renforcés sont activés au moyen d'un catalyseur formant du charbon, d'un catalyseur par transfert de phase ou à l'aide de ces deux catalyseurs.
