Abstract
The present invention provides a method for the production of chemically derivatized nanocellulose, comprising the step of a. contacting a precursor cellulosic material with a chemically derivatizing composition to form a liquid reaction mixture, and b. chemically reacting the formed liquid reaction mixture, and c. subjecting the formed liquid reaction mixture to microfluidisation, wherein the steps b. and c. are carried out simultaneously.
