PROCESS FOR THE PRODUCTION OF WATER-DISPERSIBLE POLYURETHANES

摘要

of the Invention The present invention relates to water-dispersible polyurethane elastomers having a substantially linear molecular structure, characterized by (a) lateral polyalkylene oxide polyether chains having a content of ethylene oxide units of from about 0.5 to 10% by weight, based on the polyurethane as a whole and (b) a content of , or groups of from about 0.1 to 15 milliequivalents per 100 g, to aqueous dispersions of these water-dispersible polyurethane elastomers and to process for producing these waterdispersible polyurethane elastomers.
