Abstract
Process for preparation of highly branched or hyperbranched polyamides, which comprises reacting a first monomer A2 having at least two functional groups A with a second monomer B3 having at least three functional groups B, where 1) the functional groups A and B react with one another, and 2) one of the monomers A and B is an amine and the other of the monomers A and B is a carboxylic acid, and 3) the molar ratio A2:B3 is from 1.1:1 to 20:1.
