Abstract
The present invention relates to polyamide oligomers with linear or branched chain structure with a number average molar mass of 800 to 5000 g/mol, with basic end groups which are at least partially NHend groups and carboxyl end groups, produced by condensation of polyamide-forming monomers, the concentration of NHend groups being at most 300 mmol/kg and in that these end groups are present in excess in a ratio to the carboxyl end groups.
