Method for preparing a modified cellulose ether |
| abstract |
The invention concerns a method for preparing hydrophobically modified cellulose ethers, hydrophobically modified cellulose ethers, and compositions containing hydrophobically modified cellulose ethers. The modifying agent is alkylketene dimer. The cellulose ether is preferably carboxymethyl cellulose or sodium carboxymethyl cellulose (CMC, NaCMC). Cellulose ether modified with alkylketene dimer is easy to manufacture. The modification improves the dispersability of the cellulose ether in water. |
