AbstractCompounds of the formulas ##STR1## WHEREIN: X represents oxygen or sulfur;Z represents the residue of a hydroxyl-containing moiety;R1 and R2 in formula (1) may be the same or different and individually represent alkyl, cycloalkyl or aryl and, together with the common nitrogen atom, represent a 5 or 6 member ring containing oxygen, sulfur or nitrogen or combination thereof;Nr1 r2 in formula (2) represents a 5 or 6 member ring containing oxygen, sulfur or nitrogen or combination thereof;n represents an integer having a value of 2 or greater and is equal to the number of hydroxyl groups on the orginal hydroxyl-containing moiety, the residue of which is now represented by Z.are prepared by reacting a phosphorohalidate with an amine in an organic solvent containing aqueous alkali metal or ammonium hydroxide.The compounds are useful as flame retardants for natural and synthetic materials.
