FLAME RETARDANT COMPOSITION AND TEXTILE MATERIAL COMPRISING THE SAME

摘要

A flame retardant composition comprises a phosphorous containing polymer. The phosphorous containing polymer can be produced by first reacting a phosphonium compound and a nitrogen containing compound to produce a precondensate compound and then reacting the precondensate compound with a cross linking composition. The resulting phosphorous containing intermediate polymer can then be oxidized to convert at least a portion of the phosphorous atoms in the polymer to a pentavalent state. A textile material comprises a textile substrate and a phosphorous containing polymer such as that described above.
