IONISCHE POLYURETHANE |
摘要 |
The invention relates to a process for the production of charged polyurethanes comprising reacting isocyanate groups of a polyisocyanate with hydroxyl groups of alcohols comprising (i) a first alcohol selected from one or more diols containing at least 10 carbons atoms; (ii) a second alcohol selected from alkylene diols having not more than 8 carbon atoms, alkyleneoxy diols having not more than 8 carbon atoms, polyols, and mixtures thereof; (iii) a third alcohol selected from (a) diols containing a charged group or atom, (b) diols containing an uncharged group or atom capable of charge formation and at least partially converting the uncharged group or atom into a charged group or atom, (c) polyols and further reaction of one or more hydroxyl group derived from the polyol with a compound containing a charged group or atom or a compound containing an uncharged group or atom capable of charge formation and at least partially converting said uncharged group or atom into a charged group or atom, and mixtures thereof. The invention further relates to charged polyurethane obtainable by the process, an aqueous dispersion thereof and the use thereof in a method of surface-treating a material in sheet or web form by applying the charged polyurethane to the surface of the material. |
