The present invention is related to the use of specific cyclic and/or polymeric aryl-phosphines as flame retardants and to a method for reducing the flammability of organic material by incorporating into the material these specific cyclic and/or polymeric phosphines. Moreover, the invention is related to a polymeric composition containing a polymeric material and at least one of the specific cyclic and/or polymeric phosphines in an amount of from 1 to 15% by weight, based on the weight of the polymeric material. The invention also relates to a composition comprising at least one of the specific cyclic and/or polymeric phosphines and at least one polymerizable monomer.
Cette invention concerne l'utilisation d'aryl-phosphines cycliques et/ou polymères spécifiques en tant que retardateurs de flamme et un procédé consistant à incorporer ces substances dans un matériau organique afin d'en réduire l'inflammabilité. De plus,cette invention concerne une composition polymère contenant au moins une des phsosphines cycliques et/ou polymères spécifiques à raison de 1 à 15% e poids par rapport au poids du matériau polymère. L'invention concerne également au moins une desdites phosphines et au moins un monomère polymérisable.
