A composition comprises at least one condensed phosphorus compound. The condensed phosphorus compound is produced by reacting together in a condensation reaction a nitrogen compound and a phosphonium compound. A phosphorus-containing polymer is produced by reacting in a condensation reaction a hydroxyalkylphosphonium compound to produce an intermediate polymer and then oxidizing phosphorus atoms in the intermediate polymer to yield a polymer comprising phosphine oxide groups.
