VERFAHREN ZUR HERSTELLUNG VON POLYURETHANEN |
| 摘要 |
<p>This invention relates to a novel process for the production of polyurethane via an intermediate stage of aqueous dispersions of oligomeric polyurethane prepolymers having ionic and/or non-ionic hydrophilic groups which ensure their dispersibility in water, followed by conversion of these water-dispersible oligomers into cross-linked high molecular weight sheets.</p> |
