Patent ID: 7255814

Claim:
A flame retardant and stabilizer combined, for thermoplastic polymers, comprising from 50 to 90% by weight of a component A selected from the group consisting of a phosphinic salt of the formula (I), a diphosphinic salt of the formula (II), polymers of the formula (I), polymers of the formula (II) and mixtures thereof, where R 1 , R 2 are identical or different and are C 1 -C 6 -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 1 to 4; n is 1 to 4; x is 1 to 4, as component B, from 10 to 75% by weight of a nitrogen-containing synergist or of a phosphorus/nitrogen flame retardant, as component C, from 0.1 to 50% by weight of a basic or amphoteric oxide, hydroxide, carbonate, silicate, borate, stannate, mixed oxide/hydroxide, oxide/hydroxide/carbonate, hydroxide/silicate, hydroxide/borate, or a mixture thereof, as component D, from 0 to 5% by weight of a phosphonite of the structure R—[P(OR 1 ) 2 ] m (I) where R is a mono- or polyvalent aliphatic, aromatic, or heteroaromatic organic radical, and R 1 is a compound of the structure (II) or the two radicals R 1 form a bridging group of the structure (III) where A is a direct bond, O, S, C 1-18 -alkylene (linear or branched), or C 1-18 -alkylidene (linear or branched), where R 2 independently of one another, are C 1-12 -alkyl (linear or branched), C 1-12 -alkoxy, or C 5-12 -cycloalkyl, and n is from 0 to 5, and m is from 1 to 4, as component E, from 0 to 5% by weight of an ester or salt of montan wax acid, and comprises, as component F, from 0.1 to 5% by weight of an N,N′-bispiperidinyl-1,3-benzenedicarboxamide and/or N,N′-bis(2,2,6,6-tetramethyl-4-piperidinyl)-1,3-benzenedicarboxamide, the entirety of the components always being 100% by weight.
