The invention relates to a flame-retardant polyamide composition containing: as component A) 1 to 96 wt. % of one or more thermoplastic polyamides; as component B) 2 to 25 wt. % of a diorganylphosphinic acid salt of formula (I),

Flame-retardant and color-stable polyamide molding compounds

Flame retardant mixtures comprising as component (A) 30% to 99.9% by weight of dialkylphosphinic salts of the formula (II), a and b may be the same or different and are each independently 1 to 9, and where the carbon chains may be linear, branched or cyclic and M is Mg, Ca, Al, Sb, Sn, Ge, Ti, Fe, Zr, Zn, Ce, Bi, Sr, Mn, Li, Na, K and/or a protonated nitrogen base and m is 1 to 4, as component (B) 0.1% to 70% by weight of alkyl hydroxyalkylphosphinyl organylcarboxylic acid salts and/or ester salts of the formula (I) where R1CyH2y+1 with y=2 to 8, R2, R3, R4, R5, R6 are the same or different and are each independently H, CxH2x+1, CxH2x&#x2212;1, CxH2x&#x2212;3, CxH2xCO2X, CxH2x&#x2212;2CO2X, CxH2x&#x2212;4CO2X, (C2H3CO2X)u and u=0 to 1000000, CO2X, CxH2x(P(O)(OM)R1), CxH2x&#x2212;2(P(O)(OM)R1)(CO2X) and/or CH2CO2X, where, in the R1, R2, R3, R4, R5 and R6 groups, the carbon chains may be linear, branched or cyclic, M' is Mg, Ca, Al, Sb, Sn, Ge, Fe, Ti, Zr, Zn, Ce, Bi, Sr, Mn, Li, Na, K, H and/or N-containing cations, x is 1 to 25, X is H, M, CzH2z+1 and z is 1 to 8, with the proviso that at least one of the R2, R3, R4, R5, R6 groups is not H, and the compounds of formula (II) and formula (I) are different compounds.

Flame retardant mixtures and production thereof

The present invention concerns an aqueous dispersion of multiphase polymer particles in which the polymer particles comprise at least two separate phases, the internal phase being formed by polymerization in the presence of a crosslinking agent, said dispersion further comprising a surfactant chosen from amino acid derivatives. The invention also concerns a film-forming composition comprising said aqueous dispersion of polymer particles. The invention also relates to a film obtained after application of said film-forming composition. This film dries very quickly, is water resistant, and has good adhesion, elasticity and breaking strength properties. The invention also concerns the use of said film for protecting surfaces of the skin or mucous membranes, wounds, injuries and/or skin disorders.
