Abstract: Reactive retardant 9, 10-dih dro-9-oxa-10-phosphaphenanthrene-10-0xide(DOPO)-maleic
acid (MA) was synthesized from DOPO and MA, and was used as a reactant to prepare flame retarded
alkyd resin with different phosphorous contents. The structure of alkyd resin was confirmed, and the flame
retardancy and thermal stability of alkyd resin were investigated. The results show that the fire residue
increases while the peak heat release rate(PHRR )and the total heat release(THR )decrease gradually with
increasing the mass fraction of phosphorous in the resin. For the resin containing 2. 5% phosphorous by mass
at 50 kw/m, heat flux, the fire residue reaches 12.96%, and the PHRR and THIR values are respectively
36.9% and 44.3% lower than those of alkyd resin without phosphorous. And the thermal stability of alkyd
resin is improved when the mass percentage of phosphorus is more than 2.0%0
