Developments in DOPO derivatives as FRs

A review paper summarises recent progress in phosphorus PIN FRs derived from DOPO, replacing halogenated FRs. DOPO, 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide, offers thermal and chemical stability, oxidation resistance, and its O=P-H bond enables reaction with various chemicals enabling development of a wide range of derivatives, for different applications or bringing other functional properties to the polymer, or reaction with the polymer matrix. DOPO derivate FRs for epoxies, cellulose, PET, PBT, polyamides, polyurethane, PLA, polycarbonates, polystyrene and polypropylene are indicated.
