Abstract: PROBLEM TO BE SOLVED: To provide a method for simply producing a polyurethane highly branched in a dendritic state, capable of being carried out by using a simply obtainable raw material, especially without compounding a protecting group. SOLUTION: In this method for producing a polyurethane branched in a dendritic state or highly branched by reacting a diisocyanate and/or a polyisocyanate with a compound containing at least two groups to be reactive with isocyanate, at least one reactive substance contains a functional group having reactivity different from that of another reactive substance and a reaction condition is selected so that only fixed reactive groups are mutually reacted in each reaction process.

Abstract: In a process for preparing dendritic or highly branched polyurethanes by reacting diisocyanates and/or polyisocyanates with compounds containing at least two groups which are reactive toward isocyanates, at least one of the reactants contains functional groups having a different reactivity compared to the other reactant and the reaction conditions are selected so that only certain reactive groups react with one another in each reaction step.

Abstract: In a process for the production of dendrimeric or highly-branched polyurethanes (PU) by reacting di- and/or poly-isocyanates with NCO-reactive compounds, at least one of the reactants has functional groups with different reactivity towards the other reactant and the reaction conditions are chosen so that only certain groups react together at each stage. Independent claims are also included for dendrimeric PU and highly-branched PU obtained by this process.
