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:
Polyoxymethylene diphosphonates having the formula ##STR1## wherein the R groups are the same or different and are selected from alkyl, haloalkyl, hydroxyalkyl, or (R.sup.1 and R.sup.2) or (R.sup.3 and R.sup.4) are joined together to form a ring structure are disclosed. These compounds are useful as flame retardants for organic resins in general, and especially for foamed polyurethane resins.
Abstract:
Phosphate esters having the formula Ro[-(A)M(B)NH] wherein A has the structural formula ##STR1## and B has the structural formula ##STR2## wherein the R groups are alkyl radicals, m and n are each integers from 0 to 4 and the sum of m + n is from 1 to about 4, are useful as flame retardants, especially for rigid polyurethane 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.
