    Abstract: The invention relates to a method for producing highly branched or hyperbranched polyamides. The inventive method is characterized by reacting a first monomer A 2 having at least two functional groups A, with a second monomer B 3 having at least three functional groups B, whereby 1) the functional groups A and B react with each other, and 2) one of the monomers A and B is an amine and the other of the two monomers A and B is a carboxylic acid, and 3) the molar ration of A 2 : B 3 ranges from 1.1:1 to 20:1.
