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 Mis 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.
