Abstract Copolyamides based on dicarboxylic acids, diamines and omega amino carboxylic acids or lactams are used as thermoplastic adhesives to heat- seal especially siliconized textiles. The copolymers used consist of 20 to 80% by weight of one or more aliphatic omega amino carboxylic acids or lactams having 6 to 12 carbon atoms in the chain and 80 to 20% by weight of equimolar mixtures of one or more aliphatic dicarboxylic acids having 6 to 12 carbon atoms and aliphatic alpha-omega diamines and possibly cycloaliphatic diamines having 6 to 12 carbon atoms, at least 30% by weight of these diamines consist- ing of singly branched aliphatic diamines having 6 carbon atoms.
