Title:
CARBOXYMETHYLATED CELLULOSE
Document Type and Number:
WIPO Patent Application WO/2019/111934
Kind Code:
A1
Abstract:
A carboxymethylated cellulose having a carboxymethyl substitution of no more than 0.50 and a cellulose I type crystallization of at least 50%. Ideally, the anionization is 0.00–1.00 meq/g. The Schopper-Riegler freeness is ideally at least 60.0° SR. Ideally the ratio of filtration residue is 0%–30% by mass. The viscosity (30 rpm, 25°C) for an aqueous dispersion having a 1% solid content (w/v) is ideally no more than 10.0 mPa·s.
