ABSTRACT:
A flame retardant blend, suitable for incorporation into a polyurethane foam, comprises: an oligomeric organophosphourus flame retardant, preferably an organophosphate, having a phosphorus content of no less than about 10%; a benzofuran-2-one stabilizer; and a monomeric phosphate ester containing alkyl and/or haloalkyl groups to act as a solubilizing addtive for the oligomeric organophosphorus flame retardant and benzofuran-2-one stabilizer.
