Abstract

The invention relates to a dendritic macromolecule with branches prepared from halogen cyanide units composed of a monohalogenated hydrocarbon compound comprising 3-50 carbon atoms and at least one cyanide group, the halogen and the cyanide group being separated from one another by at least 3 carbon atoms. The invention also relates to a process for the preparation of a dendritic macromolecule, comprising a core and at least one branch emanating from the core, characterized in that the process comprises the steps a) through c): a) substantially every functional group of the core molecule is reacted with monomeric halogen cyanide units b) substantially every incorporated cyanide group is reduced to an amine c) substantially every amine group is reacted with monomeric halogen cyanide units, steps b) and c) being conducted alternately.
