Novel caged phosphate esters were synthesized. Flame-retardant mechanism of poly(vinyl chloride) (PVC) blends plasticized with these synthesized caged phosphate esters was investigated with limiting oxygen index (LOI), thermogravi-metric analysis (TGA), scanning electron microscopy (SEM), and cone calorimeter tests. The results showed that caged phosphate esters improved the thermal stabilities of PVC blends: LOI values of PVC blends increased from 24.2% to 35.9%, peak heat release rate decreased from 379.04 to 258.79 kw m-2, and total smoke increased from 1877.9 to 3698.1 m2 m-2; hence, the flame retardancy of PVC blends was improved.

Substituent changes at the hydroxyl group in the title compound affect the stability of the corresponding phosphite ozonides generated at the remote phosphorous atom. The benzoyl derivative was found to have a half-life > 100 minutes at 18 deg C and is at
