Abstract: A phosphorus-containing flame retardant is produced by reacting at a reaction temperature a mixture including a metal or suitable metal compound and a stoichiometric excess relative to the metal or suitable metal compound of an unsubstituted or alkyl or aryl substituted phosphonic or pyrophosphonic acid, wherein the phosphonic or pyrophosphonic acid is in a molten state at the reaction temperature. The chemical composition of the resulting flame retardant product leads to excellent flame retardancy and exhibits high thermal stability. The presently disclosed flame retardants are useful, for example, in polymer compositions, particularly thermoplastics processed at high temperatures, over a wide range of applications.

Abstract: Flame retardant material comprising a compound of empirical formula (III)




wherein R is H, an alkyl, aryl, alkylaryl, or arylalkyl group;
M is a metal and y is 3, such that M(+)y is a metal cation where (+)y represents the charge formally assigned to the cation;
a, b, and c represent the ratio of the components to which they correspond relative to one another in the compound, and satisfy a charge-balance equation 2(a)+c=b(y); and a and c are not zero. The presently disclosed flame retardants are useful, for example, in polymer compositions, particularly thermoplastics processed at high temperatures, over a wide range of applications.
