Abstract
The polyamides are made by copolymerising (A) a mixt. of halogen-free bifunctional organic dicarboxylic acids and/or their amide-forming derivs. and a halogen-free bifunctional organic diamine, or a halogen-free bifunctional organic aminocarboxylic acid or a halogen-fee lactam, and (B) >=1 bifunctional aromatic bromine cpd. chosen from (i) an aromatic dicarboxylic acid ring-substd. by >=one Br atom or their amide-forming derivs., (ii) aromatic diamines ring substd. by >=one Br atom or (iii) a polyamide-salt of (i) or (ii), in such amts. that the resulting polyamide contains 70 mol. % monomer units contg. aromatic rings and >=0.5 wt. % Br. Process is esp. useful for prodn. of fibre-forming polyamides with good permanent flame-retardant effect without associated yellowing.
