Patent ID: 7148276

Claim:
A granular flame-retardant composition comprising an organophosphorus flame-retardant component, and of at least one binder wherein the at least one binder is selected from the group consisting of alkylalkoxylates having from 8 to 22 carbon atoms and from 1 to 80 EO units per mole of alcohol, caprolactam, triphenyl phosphate, ethylene glycol, propylene glycol, butylene glycol, oligomers of ethylene glycol, propylene glycol or butylene glycol, polymers of ethylene glycol, propylene glycol or butylene glycol, ethers of ethylene glycol, propylene glycol or butylene glycol, wherein the organophosphorus flame retardant is selected from the group consisting of a phosphinic salt of the formula (I), a diphosphinic salt of the formula (II), a polymer of the phosphic salt of formula (I), a polymer of the diphosphinic salt of formula (II) and mixtures thereof (component A), where R 1 and R 2 are identical or different and are C 1 –C 8 -alkyl, linear or branched, or aryl; R 3 is C 1 –C 10 -alkylene, linear or branched, C 6 –C 10 -arylene, -alkylarylene, or -arylalkylene; M is Mg, Ca, Al, Sb, Sn, Ge, Ti, Zn, Fe, Zr, Ce, Bi, Sr, Mn, Li, Na, K, or a protonated nitrogen base; m is from 1 to 4; n is from 1 to 4; x is from 1 to 4.
