COMPOSITIONS HAVING INCREASED CONCENTRATIONS OF CARBOXYMETHYLCELLULOSE |
摘要 |
Embodiments of the present description provide methods for increasing the concentration of carboxymethylcellulose alkali solutions that are particularly suitable for use in a high solids paper coating, barrier materials, etc. Generally described, the method includes dissolving carboxymethylcellulose (CMC) and an alkali salt in water to obtain an alkali solution of CMC. The CMC desirably has a degree of substitution less than about 0.9. The alkali solution of CMC includes CMC in a concentration greater than about 9.8% by weight, has a pH from about 7.5 to about 11, and is characterized as having a viscosity of less than about 5,000 mPa. |
