Abstract of the Disclosure This invention relates to novel phosphorus derivatives of 1,3-diethanolurea and certain polymeric reaction products such as polyurethane resins in which they are incorporated as flame retardants. The phosphorus derivatives of this invention are obtained by the reaction of various phosphorus-con- taining compounds with 1,3-diethanolurea and have the formula: Image wherein R1 and R2 are C1 to C6 alkyl, C6 to C10 aryl in which the alkyl and aryl groups can be substituted with chlorine or bromine; n is 1 or 2; p is 1 or 2; y is 0 or 1; m is 0, 1, or 2; X is oxygen or a covalent bond; R3 and R4 are, independently, H, -CH2CH2OH; or Image ; R5 is H or Image ; and, z is 1 to 100. The aryl radical is preferably phenyl or naphthyl, and most preferably phenyl.
