Abstract

Ester-modified polyamides containing of from 50 to 80% by weight of --HN--(CH.sub.2).sub.5 --CO units are obtained by reaction of .gamma.-caprolactam and mixtures of dicarboxylic acids, primary diamines and polyalkylene glycols and are suitable inter alia as hot melt adhesives and for the elastification of thermoplastic materials.
