| titleOfInvention | Process for the production of dendrimeric or hyperbranched polyurethanes |
| abstract | Dendrimeric or hyperbranched polyurethanes are produced by 1) Reaction of di- or polyols which have at least one tertiary nitrogen atom and at least two hydroxyl groups with different reactivity towards isocyanate groups, with di- or polyisocyanates to form an addition product, the di- or polyols and di- or polyisocyanates being chosen such that the addition product has on average one isocyanate group and more than one hydroxyl group or one hydroxyl group and more than one isocyanate group, 2) conversion of the addition product from step 1) to a polyaddition product by intermolecular reaction of the hydroxyl groups with the isocyanate groups, it also being possible initially to react with a compound containing at least two hydroxyl groups, mercapto groups, amino groups or isocyanate groups, 3) optionally reacting the polyaddition product from step 2) with a compound containing at least two hydroxyl groups, mercapto groups, amino groups or isocyanate groups. |
