摘要:
This invention relates to thermoplastically deformable, high molecular weight, slightly branched aliphatic polyamides prepared by the polycondensation of polyamide-forming, aliphatic diamine/dicarboxylic acid mixtures, optionally with the addition of lactams and special amino acids, in the presence of small quantities of .alpha.-amino-.epsilon.-caprolactam, and optionally their thermal solid phase after-condensation.
