Abstract of the Invention The present invention relates to non-ionic, water- dispersible polyurethanes having a substantially linear molecular structure and lateral polyalkylene oxide poly- ether chains containing ethylene oxide units characterized in that from about 40 to 95% of the alkylene oxide units of the lateral polyalkylene oxide polyether chains consist of ethylene oxide units and from about 5 to 60% consist of propylene oxide, butylene oxide or styrene oxide, to aqueous dispersions of these non-ionic, water-dispersible polyurethanes and to processes for producing these non-ionic, water-dispersible polyurethanes.
