Derivatives of polyphosphoric acid partial esters

Claim 1

A composition of matter consisting essentially a compound of the formula ##STR5## wherein R is each occurrence a remnant formed by removal of a hydroxy from a monohydroxyl compound selected from: (a) a (poly)glycol monoether of the formula ##STR6## wherein R 1 is hydrogen, methyl or halomethyl; R 2 is C 1-6 alkyl or haloalkyl, phenyl, halo-phenyl or methylphenyl; and n is an integer from 1 to 4; (b) a phenol or halophenol; and (c) a C 1-20 aliphatic or halogenated aliphatic monohydroxyl compound; provided that in at least one occurrence R is a remnant of (a); M is independently each occurrence an ammonium or substituted ammonium ion or a metal ion having valence n; m is an integer from zero to three; y is an integer equal to or greater than zero; and q' x and z are all integers greater than or equal to one selected such that (z·n)+y=x(m=4=q) and q≦m+3 and no more than 10 percent by weight of monophosphate esters or partial esters.
