Abstract
(EN)
Provided are a composite for cellulose fiber dispersion that enables the inexpensive dispersion of a cellulose fiber, particularly a nanocellulose, at satisfactory levels in a hydrophobic resin, and a cellulose fiber composition containing this composite. The composite for cellulose fiber dispersion according to the present invention is provided with a structure in which a vinyl polymer is grafted to a cellulose derivative. The cellulose fiber composition according to the present invention contains the composite and a cellulose fiber and in a specific configuration is used additionally containing, e.g., organic solvent, resin precursor, resin, and so forth.
