Hyperbranched phosphorus flame retardants: multifunctional additives for epoxy resins [PDF]
, 2019 We successfully synthesized multifunctional P-based hyperbranched polymeric flame retardants (hb-FRs) with varying oxygen-to-nitrogen (O : N) content and characterized them via 1H and 31P NMR and GPC.

Study on flame stability in oxygen-enriched ammonia/N2/O2 laminar diffusion flame
Nihon Kikai Gakkai ronbunshu, 2018 Ammonia is regarded as one of the alternative fuels because CO2 is not emitted during the combustion process of ammonia. The physical properties of ammonia are suitable for transportation and storage as a “hydrogen carrier”.

Flame retardancy and mechanical properties of poegmah compatibilized rice husk filled polypropylene composites [PDF]
, 2009 Flammability of Polypropylene, PP has restricted its usage as a versatile synthetic polymer. The addition of flame retardants will lower the flammability of PP. However, it will lower the mechanical properties.
