摘要
Phosphorus containing flame retardants are prepared by a two step process having as essential steps: (1) reacting diorgano organophosphonate with reactant comprising phosphorus oxide reagent to yield a metaphosphate/phosphonate reaction product, and thereafter; (2) reacting the reaction product of step (1) with reactant comprising epoxide to yield poly (oxyorganophosphate/phosphonate) product. Selected poly (oxyorganophosphate/phosphonate) products contain a backbone structure of repeating units represented by the average formula: IMAGE (I) wherein m is an integer from 1 to 50; R, R1, and R2 are individually selected from saturated hydrocarbon radical, alkaryl radical, aralkyl radical, and aryl radical; and R3 is: IMAGE wherein R4, R5, R6, and R7 are individually selected from hydrogen atom, hydrocarbon radical, and halogenated hydrocarbon radical. Articles and compositions such as textiles and polyurethanes are rendered flame retardant by incorporation of poly (oxyorganophosphate/phosphonate) products of Formula (I).
