Process for Preparing Derivatized Polysaccharides |
| 摘要 |
The invention relates to a process for preparing a polysaccharide derivative, comprising the steps of: (a) contacting at least one polysaccharide with at least one polysaccharide swelling agent at a temperature of at most 70° C.; and (b) subsequently, contacting the product of step (a) with at least one aromatic isocyanate; thereby preparing a polysaccharide derivative. |

1. A process for preparing a polysaccharide derivative, comprising the steps of: (a) contacting at least one polysaccharide having a crystallinity index (CI) of at least 20% as measured by XRD with at least one compound at a temperature of at most 70° C.; and (b) subsequently, contacting the product of step (a) with at least one aromatic isocyanate; thereby preparing a polysaccharide derivative whereby the crystallinity index of the polysaccharide derivative is at least 50% that of the at least one polysaccharide. |
