Extrudable polystyrene foam compositions having flame retardant properties, flame retarded extruded polystyrene foams, methods of making such foams, and products comprising such compositions and foams are provided. The extrudable polystyrene compositions having flame retardant compositions can be generally characterized as having a molecular weight (M<SUB>W</SUB>)of at least about 90% of the polystyrene in an identical composition without the flame retardant compound and a Yellowness Index in the range of from about 1 to about 10.
