New flame retardant phosphorus-containing thermosetting resins have been prepared by phospha-Michael addition of a difunctional secondary phosphine oxide, the 1,3-bis(phenylphosphino)propane dioxide, and aza-Michael addition of 4,4′-diaminodiphenylmethane. Different materials with 0–4.2% of P were obtained starting from a high oleic sunflower oil enone derivative. The kinetics of the phospha and aza-Michael additions under various conditions was investigated using model compounds and the thermal stability and flame retardant properties of the final materials were evaluated by TGA and LOI measurements.
