Abstract

The invention relates to a process for the preparation of a branched molecule by: a) reacting a nucleus molecule with a compound of a first type which contains a primary and a tertiary isocyanate group; b) reacting the product so obtained with a compound of a second type which contains a first reactive group which can be reacted with a tertiary isocyanate and one or more groups which react with a primary isocyanate and react with a tertiary isocyanate to a lesser extent than the first reactive group, followed by the alternating performance of the steps (c) and (b), c) reacting the product obtained in step (b) with a compound of the first type. The invention also relates to macromolecules obtainable thereby and to the use thereof.
