Mo3682 LeA 27,906 WATER-DISPERSIBLE, ELECTROLYTE-STABLE POLYETHERESTER-MODIFIED POLYURETHANE IONOMERS, A PROCESS FOR THEIR PRODUCTION AND THEIR USE IN ADMIXTURE WITH POLYMERS CONTAINING PERFLUOROALKYL GROUPS ABSTRACT OF THE DISCLOSURE The present invention relates to water-dispersible polyetherester-modified polyurethane ionomers containing 10 to 100 milliequivalents of ionic, preferably cationic, groups per 100 g of ionomer; 2 to 40% by weight of polyetherester groups; and 1 to 35% by weight of ethylene oxide units, in which the percentages are based on the weight of the polyetherester- modified polyurethane ionomer. The present invention also relates to a process for the preparation of these polyetherester-modified polyurethane ionomers and to aqueous compositions containing these polyetherester-modified polyurethane ionomers and polymers containing perfluoroalkyl groups.
