Abstract:
Nanocellulose dispersion compositions containing a partitioning agent and a nanocellulose, and methods of making the nanocellulose dispersion compositions, are disclosed. These compositions can promote improved dispersibility of the nanocellulose fibrils and nanocellulose crystals in polymer matrices, such as in elastomer formulations for use in tire production.
