  Provided are phosphorus nitrogen flame retardants represented by Formula III, a method of preparing the flame retardants without using any solvent, and various materials comprising the flame retardants. Rb and Rc are independently of each other selected from hydrogen, substituted or unsubstituted alkyl such as C1-C18 alkyl, substituted or unsubstituted heteroalkyl, substituted or unsubstituted cycloalkyl, substituted or unsubstituted heterocyclic alkyl, substituted or unsubstituted heterocycles, substituted or unsubstituted aryl such as C6˜C18 aryl, substituted or unsubstituted heteroaryl such as C3˜C18 heteroaryl, and acyl radical. The invention exhibits numerous technical merits such as excellent flame retardant efficacy, good compatibility with polymers, lower migration to material surface, excellent hydrolysis resistance, low smoke and low toxicity during burning, simpler preparation process, fewer by-products, shorter reaction time, higher yield, and no environmental impact, among others.
