Abstract

A star polymer is produced by converting a central compound having at least three functional groups X, an arylene compound having two functional groups Y, and a terminal group compound having a functional group Z, the functional groups X of the central compound each reacting with a functional group Y of the arylene compound, forming a covalent bond, and the functional group Z of the terminal group compound reacting with a functional group Y of the arylene compound, forming a covalent bond, the terminal group compound being used in a stoichiometric quantity that corresponds essentially to the stoichiometric quantity of the functional groups X of the central compound, and to a method for producing star polymers, a polymer mixture including star polymers, and to the use of star polymers.
