The invention relates to a star-shaped branched polyamide that has a high thermal stability and can be produced in existing production facilities for the corresponding linear polyamide. This is achieved by allowing the polyamide branches, at least three, to be formed from a multifunctional core having functional groups chosen from the group comprising amine and carboxyl groups, the amine or carboxyl groups being bound to an acyclic compound in which branching occures, if it is branched, at a carbon atom, or via an acyclic chain to a heterocyclic compound showing point symmetry. The process for the preparation is carried out under the conditions of the preparation of the corresponding linear polyamide. It proves to be possible to obtain, after shorter polymerization times, a product with mechanical properties that are comparable with those of the linear polyamide after significantly longer polymerization times. Examples of suitable multifunctional nuclei are 2,4,6-trisaminocaproic acid-1,3,5-triazine and 4-aminomethyl-1,1-octanediamine.
