## Abstract

Flame retardant phosphonate derivatives of polyalkylene polyamines are prepared having the structural formula: ##STR1## wherein R.sup.1, R.sup.2 and R.sup.5 can be the same or different substituted or nonsubstituted lower alkylene groups of about 2-10 carbons, or aryl groups of about 6-14 carbons; and R.sup.5 can also be haloalkyl of about 1-10 carbons; R.sup.3 can be a lower alkylene radical of about 1-10 carbons; R.sup.4 can be an alkyl, alkenyl, alkynyl, or aryl group of about 1-20 carbons; m is a number from 0 to 2; n is a number from 0 to 2; y is a number from 0 to 10; and x can be the same as the (R.sup.5 OH) group or the ##STR2## The preparation involves the condensation of a polyalkylene-polyamine with an aldehyde or ketone and a phosphonate or a phosphite. The condensation product is then reacted with an epoxide to yield the phosphonate derivatives of polyalkylene-polyamines.
