- Dendritic polymers are also referred to in the literature as "dendritic polymers.” These dendritic polymers synthesized from multifunctional monomers fall into two distinct categories, the “dendrimers” and the “hyperbranched polymers.” Dendrimers have a very regular, radially symmetric generation structure They are monodisperse globular polymers that are synthesized in multi-step syntheses compared to hyperbranched polymers with high synthetic complexity, characterized by three distinct areas: - the polyfunctional core, which is the center of symmetry, - various well-defined radial-symmetric layers In contrast to the dendrimers, the hyperbranched polymers are polydisperse and irregular in their branching and structure In contrast to dendrimers, in hyperbranched polymers both the tritic and terminal units also have linear units.

Example, be measured by gel permeation chromatography (GPC), wherein the measurement is preferably carried out in DMF and as a reference preferred polyethylene glycols Burgath et al in Macromol Chem. Phys., 201 (2000) 782-791). In this case, a calibration curve is advantageously used, which was conveniently obtained using polystyrene standards. These quantities therefore represent apparent measured values.

- the cooling of the products may be very important for the molecular design, it may be necessary to change the extruders in the head area, or to use certain nozzle structures. Often it is necessary here to allow a particularly gentle product discharge. This can for example be driven without a top plate.
- the starting compounds are added to the aggregates usually in separate product streams. If there are more than two product streams, these can also be bundled. Various hydroxyl-containing starting materials can be combined to form a product stream. It is also possible to additionally add catalysts and / or additives such as leveling agents or stabilizers to this product stream. It is likewise possible to combine polyisocyanates and the uretdiones of polyisocyanates with catalysts and / or additives such as leveling agents or stabilizers in a product stream. The material flows can also be divided and thus supplied to the units in different proportions at different locations. In this way, concentration gradients are set deliberately, which can bring about the completeness of the reaction. The entry point of the product streams in the order can be handled variable and time offset. As a result, the structure of the target molecules can be varied.
- the downstream of the reaction preferably rapid cooling may be integrated in the reaction part, in the form of a multi-housing embodiment as in extruders or Conterna machines.
- the following can also be used: tube bundles, pipe coils, cooling rolls, cooled chutes, air conveyors, metal conveyor belts and water baths, with and without a downstream granulator.

Then, the pastillation or crushing into a desired particle size by means of roll crusher, pin mill, hammer mill, shingles, strand granulator (eg., In combination with a cooling medium), other granulators or the like.
