Flame retardant compositions, and compositions that comprise an organic polymer and the flame retardant composition are disclosed. The flame retardant compositions are prepared by reacting ethylene diamine with polyphosphoric acid; or reacting an ethyleneamnine or a mixture of ethyleneamines with phosphoric acid, polyphosphoric acid, pyrophosphoric acid, or mixtures thereof. A 10% by weight solution of the product in water has a pH between about 2.5 to 6.0. The flame retardant compositions are non-halogen containing flame retardant compositions and do not gas undesirably during processing at temperatures of 235° C. or even higher.
