Abstract

Described herein is a process for the preparation of 1,3-dioxan-2-one group-containing oligourethanes by reacting a) hydroxy-functional 1,3-dioxan-2-ones with b) compounds having an average of at least two isocyanate groups per molecule; the oligourethanes obtainable by this process; and their use, optionally in combination with compounds containing active hydrogen atoms, for the preparation of plastics or as a binder or binder component in coating compositions.
