| abstract |
The invention relates to flame-retardant thermoset composition which comprises, as flame retardant combination, at least one phosphinic salt of the formula (I), and/or one diphosphinic salt of the formula (II), and/or polymers of these (component A), n nwhere n R 1 and R 2 are identical or different and are C 1 -C 6 -alkyl, linear or branched, and/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, and/or a protonated nitrogen base; m is from 1 to 4; n is from 1 to 4; x is from 1 to 4, and also comprises at least one synergistic halogen-containing component (component B). The invention also relates to a process for preparing these flame-retardant thermoset compositions, and also to their use. |
