    Abstract: Polyoxymethylene diphosphonates having the formula ##STR1## wherein the R groups are the same or different and are selected from alkyl, haloalkyl, hydroxyalkyl, or (R.sup.1 and R.sup.2) or (R.sup.3 and R.sup.4) are joined together to form a ring structure are disclosed. These compounds are useful as flame retardants for organic resins in general, and especially for foamed polyurethane resins.

    Abstract: Polymeric bromine-containing phosphoramidate polyols are obtained by reacting bromine with spirocyclic phosphoramidites and thereafter reacting the brominated products with a polyol, in the presence of an acid acceptor. The novel viscous polymers thus produced react with polyisocyanates to produce polyurethanes. Polyurethanes so made are characterized by improved flame-retardant properties compared with conventional polyurethanes.

    Abstract translation: 聚合的含溴氨基磷酸酯多元醇通过溴与螺环亚磷酰胺反应,然后在酸受体的存在下使溴化产物与多元醇反应而获得。 由此产生的新型粘性聚合物与多异氰酸酯反应生成聚氨酯。 如此制成的聚氨酯的特征在于与常规聚氨酯相比具有改进的阻燃性能。
