Abstract
Derivatives of polyphosphoric acid partial esters of the formula ##STR1## wherein R is the remnant of a (poly)glycol monoether, phenol or alkanol provided that in at least one occurrence R is the remnant of a (poly)glycol monoether, and M is a positive counterion of valence n are disclosed.
Claims4
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.sub.1 is hydrogen, methyl or halomethyl;
- R.sub.2 is C.sub.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.sub.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.multidot.n)+y=x(m=4=q) and q.ltoreq.m+3 and no more than 10 percent by weight of monophosphate esters or partial esters.
