    • There are disclosed multiphosphorus-containing compounds comprising phosphonate-containing or phosphate-containing phosphate esters. The compounds can be prepared by: (a) reacting a phosphonate-containing or phosphate-containing alcohol with phosphorus pentoxide following by reaction with an epoxide, (b) reacting a phosphonate-containing or phosphate-containing alcohol with a phosphorus oxyhalide, hydrolyzing any phosphorus halogen bonds and then reacting with the resulting phosphoric acid derivative with an epoxide, (c) transesterifying a phosphonate-containing or phosphate-containing alcohol with a dialkyl phosphite, oxidizing the resulting compound to yield a phosphoric acid derivative and reacting the phosphoric acid derivative with an epoxide. The compounds are useful as flame retardant additives for polyurethanes and textiles.
