Abstract
Polyamides suitable as hot-melt adhesives and containing groups derived from a polymeric fatty acid containing 70-90% by weight of dimer acid and from a triamine of the structure ##STR1## in which R.sub.1 is a C.sub.1 -C.sub.3 alkyl group and R.sub.2 and R.sub.3 are bivalent hydrocarbon radicals. Optionally the polyamide also contains groups derived from a C.sub.2-20 diamine, a dicarboxylic acid containing 6-12 carbon atoms, a monocarboxylic acid or a C.sub.5-12 lactam.
