Abstract: The disclosure provides redispersible CNC. The CNC disclosed herein is redispersible in non-polar and polar organic solvents as well as polar and non-polar polymers such as polyethylene or polypropylene. The disclosure surprisingly also provides redispersible CNC bearing improved redispersion in aqueous systems and most particularly in high ionic strength aqueous systems which usually require significant mixing energy to achieve dispersion.
