Synthesis of a DOPO Derivative to Improve the Fire Safety and
9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide (DOPO), 3,5-Diamino-1,2,4-triazole (GA), syringaldehyde, and 4, 4′-diaminodiphenyl methane (DDM) were supplied by ., China. Anhydrous ethanol, acetone, and ether were all purchased from Tianjin Damao Chemical Reagent Factory, China.
Promotion of the flame retardancy of 9,10-dihydro-9-oxa-10
As a phosphorus flame retardant, 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide (DOPO) contains a biphenyl ring structure and a phenanthrene ring structure (Luo, 2017 ), in particular introducing a side phosphorus group in the form of a cyclic O P O bond, and thus displays better flame retardancy and greater thermal and chemical stability

Supercritical fluid flame-retardant processing
A cyclic phosphorus flame retardant, 910-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide (DOPO), was used in this study, owing to its excellent flame retardancy and halogen-free, non-toxic, and environmentally friendly properties. It is widely used to impart flame-retardant properties to esters, polypropylenes, and other polymers [16, 17 ].
Studies on the Thermal Properties and Flame Retardancy
action of epoxy-siloxane with 9, 10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide (DOPO). PES was characterized by 1 H NMR and FT-IR measurements, and then it was employed to modify an epoxy resin
