Process for the preparation of aqueous polyisocyanate emulsions and emulsions obtained thereby. |
摘要 |
<p>A process for the preparation of aqueous polyisocyanate emulsions is described, which comprises the mixing of water, a cellulose derivative, at least one low, medium and/or high molecular weight polyisocyanate and a surface-active agent derived from phenylisocyanate. The emulsions obtained thereby are particularly useful as binding agents for cellulosic materials.</p> |
