| abstract |
The present invention relates to polyamide oligomers with a linear or branched chain structure which have a number-average molar mass of 800 to 5000 g/mol and contain basic end groups, at least some of which are NH2 end groups, and carboxyl end groups, and are prepared by condensing polyamide-forming monomers, the concentration of NH2 end groups being not more than 300 mmol/kg, and these end groups being present in an excess in relation to the carboxyl end groups. |
