    • Polyol adjuvants are provided which have the property of imparting flame-retardant characteristics to polyurethane foams. The adjuvants are prepared by condensing at least one mole of 3halo-1,2-propanediol and at least one mole of 1,3-dihalo-2propanol with a tetrahalo bisphenol A or, alternatively, with the reaction product of at least one mole of a phenol, a chlorophenol and at least one mole of the same or another phenol with at least one mole of formaldehyde. The condensation products are subsequently reacted with the salt of a saturated or unsaturated partial ester of phosphoric acid and optionally brominated in the latter case. Flame-retardant polyurethane foams are disclosed containing the novel polyol adjuvants.
