Abstract

Process for obtaining compounds containing at least one hydantoin group, characterized in that, in a first step, a mono-, di- or polyamine is reacted with an ester of α-halogenocarboxylic acid and the crude reaction product, in a second stage, it is reacted with a mono-, di- or polyisocyanate or -isothiocyanate.
