| 简介 |
Absorbent polymers, which are based on optionally partially neutralized, monoethylenic monomers carrying acid groups and having a re-cross-linked surface, and which are loaded with cyclodextrin compounds by covalent or ionic bonding or by inclusion are new. An absorbent polymer based on optionally partially neutralized, monoethylenic monomers carrying acid groups and having a re-cross-linked surface contains covalently or ionically bonded or enclosed cyclodextrins and/or their derivatives (I). An Independent claim is also included for the preparation of the absorbent polymer. |
