Abstract: A composition of matter is disclosed wherein the composition comprises a hydrazide compound of the formula: wherein: R1 is selected from the group consisting of alkyl, alkyl ether, and phenyl; R2, R3, R4, R5, and R6 are independently selected from the group consisting of hydrogen, alkyl, alkyl ether, and aryl; and n is an integer of from 0 to 10; and wherein: when R1 is phenyl, it is of the structure: wherein R7, R8, and R9 are independently selected from the group consisting of hydrogen, alkyl, alkyl ether, and aryl, or R7 can be combined with R8 to form a ring of 5 or 6 carbon atoms. The hydrazides are useful as stabilizers for lubricants, greases, and polymeric systems, particularly lubricating oils, as are maleated polymers that have been functionalized with them.

Abstract: Polymeric halogenated organophosphorus diols are obtained by reacting chlorine or bromine with spirocyclic phosphites and thereafter reacting the halogenated product with a diol, in the presence of an acid acceptor. These novel viscous polymers react with polyisocyantes to produce polyurethanes. Polyurethanes so made are characterized by improved flame retardant properties compared with conventional polyurethanes. Such polyurethanes are preferably in the form of foams, especially flexible foams.

Abstract: Polymeric bromine-containing phosphoramidate polyols are obtained by reacting bromine with spirocyclic phosphoramidites and thereafter reacting the brominated products with a polyol, in the presence of an acid acceptor. The novel viscous polymers thus produced react with polyisocyanates to produce polyurethanes. Polyurethanes so made are characterized by improved flame-retardant properties compared with conventional polyurethanes.
