Abstract

In the first stage, a diamine or a mixt. of >=2 diamines in a lactam or a mixt. of >=2 lactams, reacted, and the reaction prod. opt with addition further amts. of diamine(s) or lactam(s) or amine(s) and lactam(s) and also opt. with addn of an aminocarboxylic acids, is polycondensed, in the second stage, with a dicarboxylic acid or a mixt. of >=2 dicarboxylic acids or their amide-forming derivs. The first stage is effected at temps. between 40 degrees C and the decomposition temp of the unstable reaction components, pref. 200-350 degrees C, and the second-stage polycondensn is effected under the same temp. conditions.
