Abstract
The present invention relates to water-dispersible plastics precursors which are solid at temperatures below about 40.degree. C. The plastics precursors are based on isocyanate-terminated prepolymers which have been hydrophilically modified with ionic groups and/or ethylene oxide units and which contain specified amounts of isocyanate groups and --NH-- groups. The present invention also relates to processes for preparing aqueous dispersions from the solid plastics precursors and to using the plastics precursors for cross-linking dispersed plastics containing isocyanate-reactive groups.
