Abstract (en)
[origin: WO2019048311A1] The invention relates to flame retardant combinations containing - phosphinic acid salt of the formula (I) as component A, wherein R1 and R2 represent ethyl, M represents Al, Fe, TiOp or Zn, m is 2 to < 4, and p = (4 - m) /2, a compound selected from the group consisting of Al-, Fe-, TiOp- or Zn salts of ethylbutyl phosphinic acid, dibutylphosphinic acid, ethylhexylphosphinic acid, butylhexylphosphinic acid and/or dihexylphosphinic acid as component B, phosphonic acid salt of formula (II) as component C, wherein R3 represents ethyl, Met represents Al, Fe, TiOq or Zn, n is 2 to < 4, and q = (4 - n) /2, wherein the melamine polyphosphate has an average degree of condensation from 2 - 200 as component D, wherein the x-ray diffractogram of the flame retardant combinations contain the following reflections: in the angle range 2θ from 9.099° to 9.442°, from 14.765° to 15.076°, from 18.619° to 18.984° and from 26.268° to 26.679° and/or in the angle range 2θ from 5.112° to 5.312°, from 6.097° to 6.297°, from 10.082° to 10.282°, from 10.350° to 10.550°, and from 12.308° to 12.508°, from 14.765° to 15.076° and/or in the angle range 2θ from 9.117° to 9.317°, from 14.765° to 15.076° and from 18.537° to 18.737° and/or in the angle range 2θ from 8.300° to 8.500° and from 14.765° to 15.076°. The polymer compositions can be used to produce fibres, films and moulded bodies, in particular for electrical and electronic applications.
