Abstract Polyphosphate esters were synthesized by interfacial polymerization of 2,5‐bis( p ‐hydroxybenzylidene)cyclopentanone, 2,5‐divanillylidenecyclopentanone, 2,6‐bis( p ‐hydroxybenzylidene)cyclohexanone, 2,6‐divanillylidenecyclohexanone or 2,7‐bis( p ‐hydroxybenzylidene)cycloheptanone with phenyl phosphorodichloridate. The resulting polymers were characterized by elemental analysis, IR spectroscopy, solubility and viscometry measurements. The thermal properties of the polymers were evaluated by TGA measurements and correlated with their structural units. The crystallinity of all the polyphosphate esters was tested by X‐ray analysis.
