ABSTRACT:
Polyalkylene glycol vinyl phosphates having the formula: ##EQU1## ARE PROVIDED WHEREIN R is a polyalkylene glycol residue, m and n are integers from about 1 to about 100, R' is selected from the group consisting of hydrogen, lower alkyl, and lower haloalkyl, provided that if R' is lower haloalkyl, it is not monohalo-substituted on its alpha carbon atom, and Z and Y are selected from the group consisting of hydrogen, lower alkyl and lower haloalkyl. They are formed by reacting the transesterification product of a tertiary phosphite and a polyalkylene glycol with a carbonyl compound having halogen monosubstitution on one of its alpha carbon atoms. These compositions can be used to flame retard a number of normally flamable substrates.
