Abstract
Flame retardant polycarboxy alkyl and aryl phosphonates having the structural formula: ##STR1## ARE PREPARED, WHEREIN R is hydrocarbyl consisting of hydrogen and carbon and substituted hydrocarbyl including C.sub.2 -C.sub.10 alkylene, arylene, C.sub.7 -C.sub.20 alkylene substituted arylene, C.sub.3 -C.sub.20 cycloalkylene, C.sub.4 -C.sub.20 vinylene and derivatives of the foregoing containing non-labile pendant halogens, C.sub.1 -C.sub.6 alkyls, C.sub.1 -C.sub.6 haloalkyls, vinyls, ethers or C.sub.1 -C.sub.6 alkyl alcohol functions. R.sup.1 is hydrocarbyl consisting of hydrogen and carbon and substituted hydrocarbyl including C.sub.1 -C.sub.10 alkyl, aryl, C.sub.7 -C.sub.20 alkyl substituted aryl, C.sub.2 -C.sub.10 alkenyl, phenoxy, C.sub.1 -C.sub.10 alkoxy, aryloxy, or C.sub.3 -C.sub.20 cycloalkyl, and derivatives thereof containing non-liabile pendant halogens, C.sub.1 -C.sub.6 alkyls, C.sub.1 -C.sub.6 haloalkyls, vinyls, ethers, or C.sub.1 -C.sub.6 alkyl alcohol functions. R.sup.1 can also be: ##STR2## or OR.sup.4 H wherein R.sup.4 has the same definition as R, and R.sup.4 and R can be the same or different. R.sup.2, R.sup.3 and R.sup.5 are straight or branched C.sub.1 -C.sub.10 alkylene and can be the same or different. The integer represented by i is from about 2 to about 20 and the integers represented by m and n are different and are 0 or 1. The monomers are prepared by catalyzed transalkylation and the polymers are prepared by polycondensation of the monomers with diols or by polymeric transalkylation.
