Abstract (en)
[origin: ES472092A1] The instant invention is directed to a process for the preparation of dihydroxypolyurethanes containing carboxyl groups and chemically fixed ionic groups, comprising reacting (A) dihydroxypolyesters having molecular weights of from 600 to 8,000 (B) organic diisocyanates (C) compounds containing carboxyl groups and groups having a higher isocyanate-reactivity than said carboxyl groups and (D) compounds containing ionic groups and isocyanate-reactive groups wherein the products of said process contain from 0.01 to 1.0%, by weight of carboxyl groups and from 0.1 to 10 milliequivalents of ionic groups per 100 g of polyurethane.
